i just bought aluminum fuel line and put it on the frame rails of my 68 but now i think i should take it out and put steal lines instead because people are saying you need to use AN fittings on aluminum and not to use rubber hose and i don't want to flare the lines to use AN fittings. so should i just go steal and use rubber or can i use rubber on aluminum?

FWIW stock fuel lines were steel.

What is the reason you wanted to use aluminum lines. If it is because you want it to last , the original steel lines lasted forty years and the cars were driven in all kinds of weather so I would stay with the metal lines.

Yeah and they are very easy to bend

They will also get eaten up by the ethanol in the fuel and get dinged up/punctured by any sharp stones that get kicked their way. Aluminum fuel lines have no place in a car, IMO. Steel lines are safer, more durable, and not that difficult to bend. If you don't need sharp turns, you can bend them by hand. If you do, buy a $20 tube bender.

I have used aluminum lines in my cars with no problems. Go on Jegs and they have different types of hose ends so you can go from the hard line to the braided line with out flaring the tubing. Look up AN to hardline adapters. And you can get whatever you want. You can also use the rubber on the aluminum.

If you think aluminum is hard to bend , you wouldn't want to work with stainless steel lines . They are so hard that it is difficult to get them tight enough to compress the flares to seal.

Another reason not to use aluminum lines on a daily driver where salt is used on the roads is because salt will eat into aluminum . I can't wait to see what happens to the new Ford trucks that switched over to aluminum .
