    Which is better??
    I read NHRA requires braided steel lines ran along the frame rails.

    Found a site that wants $450-$550 for hard lines with a Corvette filter and compression fittings.
    I think I spent just $200 for my LS1 braided steel rubber lines with russell fittings and the Corvette filter.

    No idea how long it would take my lines to rot out though.....
    Or would bending my own regular steel lines be worth a shot ?

    I always prefer hard lines along the frame. Normally bend my own but I just bought a mandrel bent line from Inline Tube for a friends 66 Fairlane Cammer EFI deal I'm working on; there are tons of bends on that particular car, felt like saving a bunch of time. I use a short section of braided or similar with AN fittings at the tank and up to the motor to allow for movement.

    Stainless hard line is my first choice but it is tougher to bend and less friendly if it needs to be tweaked a bit. Aluminum hard line is much easier to work with.

    I have been checking out the stainless steel hard lines that Inline tube as well.

    I just installed stainless hard line from "Fine Lines" on my 70. They cost me $99, and was worth every penny. They fit well and were bent well.

    I used steel lines from Classic, then added compression fittings with barbed end to make the connections. I used fuel injection rubber hose and fuel injection clamps on the hoses to connect the pieces.

    There's actually fuel injection clamps??
    What do they look like ?

    So hard lines from the fuel regulator going up to the engine.
    Then 2 braided steel lines to the tank with 90* Russell fittings again.
    Or did you run hard lines there too JJ ?

    I know one flex line up front to the fuel rail. Just wasn't sure
    how to clamp it down, so this helps. :) Thanks.

    Here is a clamp...

    They are cheap mail ordered. Also bought my fuel injection rubber hose from Rock Auto cause it's kind of high at the parts house. I used new factory metal tube front to back. Up front, I bent a 90 degree turn up to come out next to the AC dryer. Then added the barbed compression fitting, rubber hose and the adapter from rubber to a quick connect on the fuel rail. Same out back at the filter.

    Not the best picture but you can see it.

    Hard. Braided have a limited life span and unless you use teflon lined, will cause fuel odor. I would not use braided on the frame rails, only for flex and connection purposes at either end of the car.

    EFI hose and those clamps are okay but I would trust AN fittings and real hose ends a lot more than barb and clamps. Looks nicer too. I have done both ways.

    My 79 has stainless hard line front to rear that I bent myself. It does not bend nice and easy but it can be done. It connects to braided using compression to AN fittings.
