Fuel Line...What size?

I have a flat 6 dodge, and I am just finishing re-finishing my gas tank, and I want to run all new fuel line from the tank to the pump. What size fuel line should I get? 1/4, 3/8? Is aluminum ok? Is an inline filter before the pump ok? Thanks!!!

 

I use 3/8, and a in-line filter.

 

I'd run 5/16 or 3/8 since that is what most of your inline filters are sized. I like a filter after the tank myself run along the frame rails.

 

Agree with the above.

 

Not aluminium. Use steel bundy tube.

 

5/16 steel will be plenty.

 

5/16 was standard issue to supply fuel to the 230 c.i. 6 on the Dodge trucks . I would use 5/16ths rather than risk starving your engine.

 

I used 5/16" in a 401 Nailhead with two 500cfm AFBs and never had a fuel starvation problem.

 

I ran mine last night, used 3/8 brake lines for delivery...


and 5/16 return...shhh don't tell anybody

5/16 is more than you will ever need for fuel delivery.

 

Whatever you do make sure it's steel and not that soft black **** the parts stores are selling now in pre-made lengths. That stuff might be okay for fuel line in a car running a carburetor, but I had a bear of a time getting connections to seal using it for brake lines. Had it all done and bled and made a hard stop and it started a leak at one of the unions, I had to crank it down for about the 5th time to seal it up again.

 

The stock pick up tube in my wagon tank is 5/16, so thats what I ran. They are right with the steel tubing, the only way to go, you can buy a 25' roll for dirt and do it in one piece, works well
