I would like to change my fuel tank to under the bed. As some of you know I have a mid 70's Blazer fuel tank. What did others use for a hard supply like fuel line? Was it a pre bent unit or did you bend it your self?

 

I used steel brake line, bent it as it needed to be.

 

My tank is stock. I also used steel brake line 5/16" in believe. These days steel brake line has a protective coating on the outside to resist against rust. Easy to bend, readily available with good fitting selection and looks good. I used a short section of flexible line at the fuel pump.

 

Brake line here too. I also used it for my transmission cooler lines. It's cheap and easy to work with...

 

Same here. Steel brake line.

 

I used copper for my fuel lines but switched to brake line after the restoration.

 

I use Brake lines on most on most of my projects. But when i wanted some serious fuel lines for my mustang i used aluminum, with AN fittings.

Brake line here too for fuel,transmission cooler and vacuum lines.

 

Its good that most of you guys are using steel lines. My truck is not stock and the distance from the gas tank to carburetor was not far so I used a good quality rubber line. Well, when I removed the line a year later it had deteriorated inside from the ethanol in the gas. I replaced it with a marine grade rubber line that is resistant to ethanol. I haven't had a problem since.

 

Since my truck is diesel, I used a 3/8" plastic air line that is used on heavy duty trucks.

 

IMHO it's not a good idea to use copper or aluminum lines. Both work harden from vibrations and will fail without warning. My panel had a rear aux fuel tank installed at the rear sometime in it's past, the tank had been removed before I got it, but the aluminum fuel line had been left in place. When I went to take it out, it snapped at nearly every clamp or where it passed thru a crossmember.

 

What I was looking at is rubber fuel line from the tank to a fuel filter on the frame rail then another short rummber from the fuel filter to hard line and then up the frame rail to the pump. May also add a see threw fuel filter near the carb.
