Ordered a new one and, of course, it's different from the original one.  Anyone know if this will fit and work correctly for my '85 with 351?  ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

That looks to be an automotive pump because of no diaphragm failure overflow hose connection ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

It is. Ordered while still on the lake yesterday. Getting a marine pump will cost me about $250 plus probably 2-3 weeks time to get here. I can return this if it won't work. ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

Sander, I feel you are going to have to face the $250 and get the proper pump. That pump you did get besides being non marine as Gary mentions, looks like it's for a newer engine with supply and return fuel connections. Where have you been getting your parts from being in South Africa? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

You can make it work temporarily..... You have to change out some fuel lines to rubber. Keep all the original hard fuel lines as is, so you can reuse them when the correct marine pump arrives. ------------- If you're going through hell, keep going http://www.correctcraftfan.com/diaries/details.asp?ID=2999" rel="nofollow - 89 Ski <a href="http://www.correctcraftfan.com/diaries/details.asp?ID=5685" ta |

Thanks for the info guys! Just recently I ordered the module for distributor and rotor. Cost $97, but $250 before I had it in my hands. Still sick of that so figured I'd try the one they had locally. Hoping to find someone who can bring the pump from the US now. Pete; at high rpm it starts stuttering, not enough fuel reaching carb, and sometimes engine shuts off. Carb seems OK. Not able to measure psi's, but mechanic was confident it's the fuel pump that's failing. ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

Sander, You mentioned you didn't have a way to measure the pump pressure but, all it takes is a plain mechanical gauge like you would find on a air compressor and then a T fitting. You must have some kind of industrial supply for the gauge? Go for a low psi scale like 0 to 15 psi. If all you can get is a gauge in bars' that's fine too and will just exercise our math! Is your mechanic guessing or did he actually see what pressure the pump is producing? Is the pump discharging any fuel to the flame arrestor via the safety (most are clear) tubing? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I think fuel starvation has been diagnosed many times on here to be related to the fuel pick up at the tank. Others with experience can chip in but it seems to me there is a check valve at the tank that plugs or sticks causing engines to starve for gas.. Do you know that your fuel filter is good, has it been replaced? |
Posted By: 8122pbrainard
Date Posted: October-18-2015 at 3:39pm
Mark, You must be thinking about the anti-siphon valve. It's not a true check valve but rather a USCG required device. In case of a leak in the fuel line from the tank, it prevents filling the bilge with gas. Yes, they do plug up. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

$250? Try this one for $89 from http://www.skidim.com/FUEL-PUMP-ASSEMBLY-PCM-FORD-302_351/productinfo/RA080002A/" rel="nofollow - skidim I would also look at a properly adjusted floats first. If your float is too low, you will starve for fuel at higher RPMs. JQ ------------- Current 2003 Ski Nautique 206 Limited Previous 2001 Ski Nautique Open Bow 1994 Ski Nautique Open Bow Aqua skiing, ergo sum |

Borrowed a pressure meter today. It didn't do a thing, needle didn't leave "0". Must have done something wrong, though I can't imagine what. So that didn't help much. At all. Pete, I didn't see any fuel going to the flame arrestor, though hard to tell cause tubing isn't that clear. Don't know what that indicates though? JohnnyQuest, after shipping and handling and duties, that $89 will be close to fore-mentioned amount I'm afraid.

Hi Trip Why don't you hook up a 5 gallon gas can temporarily, directly to the suction of the fuel pump and see how it runs? Use a piece of clear tubing and you can see if the pump is sucking from the can and runs good. If it doesn't suck, then it's probably pump related If it sucks and runs good, look at the anti siphon valve on the tank or the line from the tank to the pump or a filter if there's one on the suction side. Won't cost any outrageous shipping charges to check this stuff. KenO |

Sander, Do you remember what the scale was on the gauge? The fuel pump delivers around 6 Psi and the reason I suggested a 0 to 15 psi gauge. If the gauge has a higher scale, it would be hard to see any pressure. Not seeing any fuel going to the arrestor is good. On a marine pump if the diaphragm inside the pump develops a leak, fuel goes back to the carb instead of into the bilge or the engine crankcase. It's a USCG thing.
Kens idea isn't bad but only from the standpoint of if the engine "runs good". You will not be able to tell if the pump is bad or going bad from looking at fuel in a clear piece of tubing. You may see flow but at what pressure and difficult to detect the direction of flow. Besides leaks in pump diaphragms, there are also check valves inside the pump. If they plug up from say varnish, fuel will be pumped back and forth instead of just to the carb. Yes, "runs good" is what you really want but also you don't want to be stuck out in the middle of the lake! ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

If the pump is working properly you shouls be able to take the fuel line to the carb off and fill a jar with gas while cranking. If it can't fill the jar it has problems. ------------- The value of money spent on new adventure far exceeds the value of money saved for the future |

Maybe I should simplify this Hook it to the can,use whatever tubing you want if the problem goes away, it's not the fuel pump. KenO |

Jack, Sorry but I don't agree. You are forgetting the pump pressure needs to overcome the needle and seat. The pressure won't be much but with the fuel line disconnected, the pump will not see this required pressure. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

All of the above checks and suggestions are proven to find the problem. Don't start throwing parts at the boat to find the issue!!! If the fuel Pressure is 5-6 psi. at idle (650-700 rpms check it at rpm when the problem is occurring. I had a customer's boat act the same way. He brought it to every marina in the area and all of the fuel system components had been replaced, Once the boat was on plane the engine would cut-out and misfire. Fuel pressure at rpm would drop to 1 and then .5 psi. and stay there until the fuel fill was loosened. The problem was a spider nest in the tank vent screen!!! When fuel is pulled out of the tank by the pump air must get in to prevent creating vacuum in the tank. The pump cannot pull sufficient volume against a vacuum. It's worth a shot take a look at your tank vent from the outside, be sure it is clear of all debris!!! |

Thanks again everybody! Think I'll have a chance to go to the boat tomorrow. Will check vent screen, but if that's clogged I'd also have problems when filling up the tank, 'cause air can't escape, right? And also I'll let the pump suck straight from a gas can. Pete, indeed the gauge that I had went to 50psi, so that' probably the reason the needle didn't move a bit. Tried to find another meter but only found one with even larger scale (100psi). Found a friend who's coming down to CR this weekend who will bring me a new pump. Might not be needed, then I'll just keep it as a spare, or maybe sell it. Figured I could get it now for $89. If I waited and it did turn out to be the pump it'd cost double to triple. Dying to figure out what it is. And to ride!

The latest; checked the air vent, looked fine, blew in it and air came straight back. Then disconnected fuel line at water separator and put it straight in gas can. Ran boat at WOT, and.... no problem whatsoever. Reconnected fuel line, ran boat at WOT, and... no problem whatsoever! So my best guess is that there was something stuck somewhere in the vent-hose and that I blew it lose. Hoping to run the boat tomorrow for a bit longer, so I'm very interested to see how it behaves! As usual, CCFan'ers were right.  Let's hope the story ends here.

Problem persists. Have only found pressure meters that read up to 100 psi or so. I'll keep looking for one. Or I might just change the pump to see if it solves the issue, since I have a new one anyway. How hard or easy is it to change it, for a not very mechanically inclined person like me (I'm always very pleased already when I managed to change the impeller or change oil, that level :p) To be continued.... ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

Sander, It's pretty much a bolt on install and as long as the pump is the same, you won't need to deal with rerouting fuel lines. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Well that wasn't too bad. Though it didn't fix the issue... Happened again: after about a half hour of use, in a turn the engine starts running bad and almost dies. I leave it idling for a minute and we're good for 5 minutes or so, then happens again. Again idle a bit, go, then the same starts happening in straight line too. I cleaned out the tank, changed the in-line fuel filter, blew the air vent for the tank at the back of the boat. And changed fuel pump now. Looks like something is clogging up the fuel supply somewhere. But where?! If I take the pick-up out of the tank, do I need 4200 to put it back? Cause I don't have it atm (and can't get it within a couple hours' drive). ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

Yes it is at this point much more likely to be poor wiring to the dash causing excessive voltage drop than it is to be a fuel pump not pumping enough. Do the basics, voltage check, tune up, carb cleanout... all much more likely than a fuel pump issue. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |

Intermittant issues like this could be water in the fuel. If it has a water separator before the fuel pump, did you check it to make sure it hasn't collected and water? I like the 5 gallon gas can test. If it runs good, you know your problem lies between the fuel pump and tank. You can eliminate fuel pump, carb issues, and electrical issues. When you say you cleaned the tank, what did you do? Cleaning the fuel tank is big job. It requires removing the tank, empting all the fuel. Washing it out with soapy water and repeated rinsing. After that, it needs to be dryed out and reinstalled. |

If I'd pull the pick up out of the tank, what do Iook for, and does it need to be sealed with 4200 when putting back in? I tried to find pictures or the part at skidim but can't find anything. Is it listed under another name maybe? @mamigazc there's no water in the tank. It also does have a separator. Yes I took the the tank out of the boat and cleaned it with mineral spirits. ------------- http://www.flyzone-cr.com" rel="nofollow - FlyZone Costa Rica Wakeboarding http://www.correctcraftfan.com/diaries/details.asp?ID=8406&sort=&pagenum=1" rel="nofollow - 1997 Super Sport |

I have a 0-15 psi fuel gauge. It has a 1/8 NPT male fitting on it. I would sell it for $15 plus shipping if you are interested? I like to use a product called "seal all" when assembling fittings that contact petroleum. Its petroleum and alcohol resistant. Maybe someone else can comment, but I have never heard of 4200 in applications for sealing things in contact with petroleum. |

Update: I had the same issue as TRIP and changed the antisiphon valve and ran the boat for about 2-3 hours with no issues...Got to half tank and started having the same issues...Boat would starve for fuel and die....Took the tank out this weekend after returning from the lake and found that the pickup in my tank was also nasty and a little clogged. I blew everything out with compressed and will keep everyone posted when I have a chance to return to the lake. ------------- Jeremy Oliver 2001 Nautique |
