 Topic: Replacement Fuel PumpPosted: August-14-2006 at 9:16am |

So, wouldn't the clear inline work just as well as a visual aid if it was placed on the suction side of the pump?
But, my fear would be that the filter could crack and start leaking fuel. Since the pump and thus the cracked filter is lower than the fuel level, it potentially could siphon all the fuel out of the tank. For this reason, before I installed a filter/seperator, I installed the inline filter at the top of the fuel tank. Sort of kills the visual aid part of the equation, but would act as a vacuum break if it started leaking. The irony of all this for me is that I was breaking other marine fuel safety rules at the time, so I guess it was a moot point. |

Right, the clear inline is for visual purposes. My water separator filter is just before the fuel pump. I doubt anything would get pass it and end up in the see through filter.

the clear inline filter is more of a visual verification that fuel is flowing than for filtering but could be used as an indicator that they need changed as you could tell when it starts to build up dirt in the clear filter.

Hi DavidF,
I hear ya. I guess I'm trying to be too curious with the filtering. I can pick up some metal fuel line this weekend instead of running the rubber hose. The fuel/water separator is definitely a filter & thus I shouldn't really need the in-line. It's good to have people to keep me honest and keep another CC Mustang on the water. I guess I've gotten complacent since its been running this way for so many years. Thanks Again. |

Bhgran:
What 79Nautique (I can't believe we agree on something) and I are saying is that you should install a solid steel line between the pump and carburetor. Marine (or aircraft) grade rubber fuel line is acceptable on the suction side (from tank to pump). I could be wrong, but most, if not all, conventional water seperators are also filters. But, if you insist on the cartridge type filter, put it on the suction side of the pump. Now, the marine grade rubber fuel line is very thick and is thus sensitive to the correct size hose clamp. Too large a clamp will not evenly compress the fuel line and an air leak is possible. |

Thanks. That's the plan. I have installed a NAPA Fuel/Water Separator on the suction side & will install an in-line cartridge type filter between the pump & card. I have used braided flex fuel lines on my RoadRunner and my Belvedere. They work real well against heat & won't burst. Besides, they look purrdy.

marine grade hoses are typically thicker walled hoses compared to automotive grade and most transmission applications are for higher pressures with crimped metal flared ends, cord reinforced, and heavy walled lines.
You are better off installing the filter on the suction side with rubber marine grade hose and a steel line running to the carb from the pressure side of the pump. |

David, the fuel line in question is not fuel line hose, it's extra thick, I think transmission hose.

Almost all gas has 10% ethanol in it and has been since the 80's they just don't have the stickers they use too to identify it when it first came out. If you look around the pump it's on it somewhere in the fine print.

Hey 79, a 10% ethanol blend would be ok to run in my 318? I can get that cheaper in my neck of the woods.

using stabil all of the time is a waiste of money, It will not dry out the water in the fuel if it is present. Thats what the separator is for to trap the water that is in the fuel. Low levels of of ethanol (10%) isn't a bigg deal and won't eat up the hoses. Now if your trying to use E85 thats a whole different ballgame. If your wooried about stick a piece of hose a jar of Everclear, grain alcohol, and see how long it takes to break down the hose.

I'm looking for either steel or braided flex fuel line to replace the rubber. When I bought the boat in 1986, it had rubber line and I just never upgraded it. Considering the pummp puts out at 5-7PSI, I didn't worry about it. Now that I know it's a USCG requirement, I'll change it out once it is running for more than 10-sec.
Thanks for the feedback. |

I am not a big fan of having a rubber fuel line on the pressure side of the fuel pump in a boat. If the rubber line should develope a leak, you might be pumping fuel into the bilge and not know it until it is too late. Most marine applications use a steel line from the pump to the carburetor. |

Thanks for the feedback. Went to local Correct Craft dealer here in CT and bought the same fuel pump for $5 more than Whitelake. I spoke with one of the service guys and I explained my problem. I was shocked that he offer a few suggestions. I told him that my plan was to run a hose from the fuel input on the pump to a container of gas to see if my restriction is from the tank to the pump or from the pump to the carb. If the boat runs off of the container than my issue is further aft. He asked if I had replaced the rubber fuel line since ethanol will eat away at the old fuel hose material. I hadn't yet but I will now. He also recommended using stabil all season long. Said it does a better job than dry gas when mix with ethanol based fuel. He gave me a couple of articles from Cobalt and Merc-Cruiser regarding the use of ethanol based fuel. Haven't read them yet, will do that tonite. Since I'll be replacing the fuel line, I'm gonna check ouy the siphon tube too. This has been a bad season for the ol' Mustang.
Thanks again for the suggestions. |

Get one of these see through filters, you know when you have fuel going to the carb.

Fuel pump should be easy to find. 302 and 351 both use the same pump.
go to www.whitelake.com and click on store and then fuel. |

I have a 1973 Mustang with the Crusader Conqueror 220 (Ford 302CI). Have had a ton of issues tail end of last season most of this season. Initially thought I had an electrical problem but have re-worked the ignition system inside & out. Boat starts great, 2-seconds later it dies. I can start it again, 2-seconds it dies. Seems to be fuel straved. I have had to replace in-line fuel filters mulitple times and it seems to help for a short time. Installed a NAPA fuel/water separator, ran fine for short time but now can even leave the dock. Is it the Ethanol? Not getting good fuel flow so I am looking for either a mechanical replacement or upgrading to an in-line low pressure electrical fuel pump. Any sources for finding these? I have looked at "iboat" but the only pump that looks anything like mine is for a Volvo.
Any help would be much appreciated. |
