How do you replace fuel lines on a 1966 Impala?

Do you have to remove the frame? I have a 327 motor, donít know if that helps.

Thanks.

No the fuel lines are held onto the frame rails by spring steel clips.

I replaced mine earlier this year, it's pretty straight forward. I got a one piece unit from the vendor which comes doubled over in a big box. Just take it out and carefully unbend the line and determine how to feed it back and forth to get it in the proper place. Short rubber line at the tank, and short rubber line at the fuel pump and you're all done.

How did you twist it up and over the crossmember at the back in front of the tank?

Pretty much what you just said, twist, wiggle, shimmy back and forth - and a whole lotta swearin! That particular area was tight, but you just get it started and bend and unbend as needed. I only jacked up the pass. side, it might have been easier on a lift. It's not really a knuckle buster, but you'll definitely earn a few Labatt Blues after you tighten those hose clamps. I did it by myself in a couple hours. Good luck, and have at it!!

Ok, thanks. I have an original fuel line in nice shape, 3/8" (I have 5/16" now) and I want to replace it. I have a lift, and I will likely swap diffs this winter to put in a posi so I was thinking that might be a good time to do it. I looked at it on the lift one day and didn't think it could be done without major bending but that gives me hope!

Thanks again.

Oh, and I can't stand the taste of beer so that won't be an issue!
