Fuel pump to carb fuel line ?

Does anyone make a pre-bent fuel line for a SBC, from the fuel pump to carb?

You’ll need to make one.
Easy to do.

Geezer#99 is correct, creating your own line (bending/flaring) is very easy to do but will require you to purchase the specialized tools to do the job (flaring tool, bending tool) You may be reluctant to purchase the tools at first but you will be pleasantly surprised to find they come in handy often. My advice, spend a little extra $$ and get a quality flaring tool. You do not need to spend a lot on a bending tool and you will find there are many ways to bend line without one. You can make your own jig, use your hands, etc. I have found that aluminum fuel line works very well, it's lightweight and very easy to flare. You can purchase a roll from Summit or Jegs, it's cheap enough that you can make a few mistakes and have plenty left over for other projects. Another tip, use some small gauge wire or welding rod to help map out the route your line will take first, then use this as a reference when you bend your line. I used the Edelbrock single feed fuel line to start the job at the carb and finished it using aluminum fuel line and -6 AN fittings.

Re: Fuel pump to carb fuel line ?

Fuel lines need a double flare.

Re: Fuel pump to carb fuel line ?

With a stock mechanical fuel pump the fuel pressure is anywhere between 4-8 lbs (depending on setup). So fuel lines do not require a double flare, single flare is plenty.

Each unto their own then. As for me, if the line contains a highly flammable material at any pressure whatsoever, I'm going with a double flare.

Re: Fuel pump to carb fuel line ?

On an eddy carb the last thing to do is bend up a solid line. Use rubber fuel line until you determine whether you need a fuel regulator or a heat spacer.. saves a bunch of frustration.
I bought a tubing bender at Home Depot like this one from harbour freight. Used pre flared pieces of tubing in short lengths bought at the parts store.

Re: Fuel pump to carb fuel line ?

I like the aluminum idea for fuel lines.
Anyone who has done this, what fittings did you use?

Re: Fuel pump to carb fuel line ?

Although, I have seen some discussion about aluminum and ethanol fuel.

1.Fuel line: I bought a roll of aluminum fuel line from Jegs (example: https://www.jegs.com/i/JEGS/555/1510...RoCAmcQAvD_BwE)
2. Fittings: I used -6 AN fittings in Black from a combination of Earls and Summit, both are available at Summit Racing.
3. If you run an Edelbrock carb you can purchase their fuel line kit (single feed or dual feed) for a nice clean install. (https://www.summitracing.com/parts/edl-81343)

Aluminum fuel line is very easy to work with and makes for clean easy bends with a simple tubing bender and super clean flares using a simple flaring tool. I have been running this setup for thousands of miles on a daily driven Suburban without issue.

Thanks, and no issues with ethanol fuel?

Re: Fuel pump to carb fuel line ?

I've been running this setup on a daily driven Suburban for many thousands of miles over many years without issue. I believe it's when ethanol based fuels sit for very long periods of time that anything that comes in contact with it also suffers. This could be anything from rubber to aluminum to steel etc.
