Fuel line
 

1960 suburban with sbc350 with 4 barrel eddy, manual pump. Tank is Tanks, inc. 38 Chevy tank with fuel supply coming out of threaded port on lower rear of tank. Line from pump to carb is braided with an fittings to hard line at top of motor with eddy fuel filter then hard line to carb.

Due to a few changes, such as tank and not liking my main inline filter being up under frame rail in front of rear axle, it's time to rerun things. Im currently aluminum line off rear of tank and up and over to meet the steel line where factory setup was with original tank. I ran all new steel lines 3yrs ago, but couldn't get a bend to go through frame rail so split and installed inline filler there. It's been a PIA to get to to change and a source of leaks. I also don't like having the rubber line going from aluminum to steel, I had to replace all the rubber due to cracking in 3yrs. Not understanding that, maybe parts store had crap hose.

What's everyone using? Aluminum, is obviously super easy to work, but will it last? Thought about finding some steel coil to protect it, like is used on brake lines, where it passes through any questionable spots. I can once again try steel line. Friend has some sort of braided? line going from tank to throttle body on his ls motor. I worry about that if aluminum it's frowned on.

I do want to relocate main fuel filter and possibly install either a manual or electric fuel shutoff valve, so trying to figure that out as well. Two fold reason on valve, one, it'd make future filler replacement simple if under truck. Tired of wearing fuel, yes if rubber hose I can clamp, but trying to eliminate the rubber. Two, if parking outdoors for long I could shut fuel off to stop a thief from going far. Granted, unless electric, I'd have to crawl under to do....hmmm! Just a thought.

Looking for ideas, suggestions.

I don't see anything wrong with using aluminum, you'll just have to make sure that it is well protected from rubbing and vibration. I don't like the idea of going from steel to alum. and back again though, but that's just me.

I guess PTFE is possibly what's on friends truck. That's what I'm leaning towards for simplicity and hopefully no future problems, but still looking for feedback.

The nickel copper line would be the way to go and hard line it. It can be bent and flaired easily and will never rust. With the amount of ethanol in todays fuels I would not use aluminum.

Either would I.

Re: Fuel line
 

I went with PTFE lines and AN fittings. Pretty straight forward to install, and easy to make changes if needed.

I don't love going from one to other, but I needed a custom bend coming of the tank and the aluminum was easy to form and I figured I'd replace later and could be a good template.

Re: Fuel line
 

what brand did you get?

Re: Fuel line
 

I second avoiding the aluminum lines...the ethanol might wreak havoc on them if the truck sits for periods of time. If it is a daily driver, maybe it would be ok. Also, if you go with annealed copper, don't directly connect to the aluminum tank as there most likely be some galvanic action happening there.

Just my thoughts.

I bought them through Hot Rod Fuel Hose

When I plumbed my truck, i used the Push Lok hose. Easy to route and will withstand the fuel pressure and different types of fuel.

How does aluminum fair with ethanol?
How will it it fair with e15 or maybe even e85?
