After installing the Holley 4160 last night, I tried to attach the fuel line from the fuel pump. Unfortunately the carb now sits atop an Edelbrock Performer intake. The fuel line is just a tad short...it's connected, but way too tight for my liking. Skidim has a universal 31" rubber version, but that runs around $65. Is that my only option, aside from making my own line? ------------- 1985 Ski Nautique 2001 |

I just bought the SkiDim 31" line for my Chevy powered engine (Performer + 4160 Holley on order).
I'm guessing yours is Ford powered as the Chevy metal line will not reach a Holley carb with out a series of adapters. I looked at the line to move the Holley fuel inlet to the Chevy side and many other parts on Summit / Jegs / Race Boat website. While some looked promising nothing looked as simple and secure + USCG approved like the 31" Ski Dim line for my application (My pump is on the rt and carb fuel inlet on the left). Most automotive performance stuff converts to Hoese barb or AN/JIC Hydraulic line type fitting. Hopefully the ford guys have a quick trick to help you out. Their are many diffeent short metal inlet line adapters for the Holley but none that would help me. ------------- Michael ....

3/8 steel brakeline at your local auto parts store, if you can borrow a tube bender and a double flare tool you can make your own for about $10. ------------- You can’t change the wind but you can adjust your sails |

all that is required is taking some of the bend out of the line so that it is a little longer. If both ends are attached and tightened then it's good to go, Don't understand what you think is too tight, too close to the block maybe? The Tubing will bend so just adjust the bends and get it away from the block and you'll be fine with the current line. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

My dad borrowed a tube bender today and TRIED to alter the fuel line. He was going slow and easy...and making good progress. Until the final big bend. Just a slight bit of pressure snapped the line. I'm not sure if that's because of its age, or it's to be expected for that thickness of line.
When I said earlier that it was too tight, it was up against the alternator - and that was from the original bending of the upper section of line by hand. Now I've got to decide between ordering an OEM piece from skidim, or finding a double flare tool and making my own. ------------- 1985 Ski Nautique 2001 |

Craig,
Get some brake line like Alan mentioned but pre flared. You may want to get several lengths in 1" increments. Start with the length you think will work. If good, take the others back. Double flaring is a PITA and sometimes even a "art"!! Bending can be a challenge too and depends on the type of bender used. With steel tubing, you need a top of the line bender. ------------- /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 < |

The double flare will certainly be a bigger challenge than the bending.
As Pete suggests, if brake line is available in the right length (or a couple of inches longer) bend it with the pre-flared ends in place......you can always add an extra little bend to take up length. As I remember, when I made up a fuel line a couple of years back, the auto parts store only had brake line that came in 6" size increments. |

Thanks to Jody at FL Inboards, I got another fuel line (which I still owe him for). This one was much easier to shape. Got everything buttoned up and headed to the lake yesterday for the test. The ONE part I didn't replace/refurb, the fuel pump, is bad. I'm not getting enough pressure from it. Another holding pattern till I can get one in... ------------- 1985 Ski Nautique 2001 |

My fuel pump is beginnign to leak oil. Looks like I'll need one too.
Any preferd place to shop? ------------- Michael .... I'm the black sheep ~ 1984 Dixie 299 Super Skier (350 Chev PCM / counter rotation / Velvet drive) Open Bow. |

Did you mean to say leaking gas? If gas, you need a pump. If oil then the gasket at the pump flange where it bolts to the engine block.

Pete,
It is odd I'm getting oil in the vacuum line to the flame arrestor. Checked and double checked but it is oil / not fuel. I assume their is a gasket sealing the pump arm from the rest of the assyembly. ------------- Michael ....

Yes, there is a gasket between the pump and the block. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

Yes but this gasket only seals off the block to the outside. Michael, Sounds like the oil is internally making it past a leak in the diaphragm and into the vent tube.

Didn't have that problem. Just not gas going up the fuel line to the carb. 25 year old pump, what did I expect?  ------------- 1985 Ski Nautique 2001 |

My pump was 6-7 years older than your 2 and it didn't leak from even the first diaphragm and still put out 4.5 psi.
Too bad 4.5 psi is not enough  ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

Come on guys, too simple.........
How can oil get in the "sight tube" from the lack of a gasket. There are two diaphams with a "marine fuel pump" my vote is the lower diaphram is compromised...... ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

Of what use was the above statement .... 4.5 is ample for 90 percent of the carbs out there.I am running a stock PCM fuel pump on her 331 and have spun it 6500 rpm with no fuel starvation issues.What makes you say that 4.5 is not enough??? You have other fuel delivery problems and a Band aid was used.Do you have a PCM Engine Manual.If not,I would suggest you add this to your marine library.

Thanks Pete & Boat Dr. ~ New pump ordered and on the way..
I considered a rebuild kit but the fuel system is not the place I want to make a compromise. ------------- Michael .... I'm the black sheep ~ 1984 Dixie 299 Super Skier (350 Chev PCM / counter rotation / Velvet drive) Open Bow. |

Is pressure ever an issue with a pump?
A float bowl is vented and has no dependancy on pump pressure for operation ~ only flow. ------------- Michael .... I'm the black sheep ~ 1984 Dixie 299 Super Skier (350 Chev PCM / counter rotation / Velvet drive) Open Bow. |

No it's not dependent on pressure but, pressure is a indication of flow. Since dropping a pressure gauge in line is easy and inexpensive as compared to one of the flow measuring devices it's a common diagnostic tool. ------------- /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 < |

25 years!!! You must be having a good one. How long do these pumps usually serve us? |

I did my pump on my 54 in 2008. That's 54 years. I know it was original due to the paint that was still on it when I bought the boat and rebuilt the engine. ------------- /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 < |
