Fuel line for Holley to Edelbrock Intake - Update

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.

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?

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.

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.

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...

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. Get back to us.

Yes, there is a gasket between the pump and the block.

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

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......

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.

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.

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.
