    Replacing the fuel lines
    « on: January 02, 2009 - 02:20:53 PM »
    I just got my car up and running after removing the Air shocks.  My daughter and I went for a morning trip around town for errands and stuff and got back in the garage to find a small puddle of gas forming.  I looked under and thought it was the hoses to the sender unit.  Nope.... there was a small stream of gas shooting out of the steel (mainly rusted) lines.  Looks like they will need replacing.  Any tips?  When I did my vette's I ordered premade lines (bent and pre cut) are there any premade lines available for the 73 challenger that won't cost an arm and leg?  Or should I just cut and bend my own?  Also, any gotcha's that may surface?

    I went with Year One without knowing any better.   

    They were pre-bent. My advice is to start by taking off the rear passenger's tire. You will need to feed the long half of it under the car towards the front, the shorter side will need to be messaged up around the wheel well and over to the sending unit. Hopefully you can re-use the clips from your old line that hold it to the frame.

     :iagree:

    You can get 3/8" stainless pre-bent lines from inline tube for $99. If you don't mind doing some of the work yourself, you can also just buy a roll of aluminum 3/8" tube from summit and do the bending, aluminum tubing is pretty easy to work with...

    If you have 5/16 lines, you'll need the 3/8 clips to upgrade, along with a 3/8 sending unit.    :grinyes:

    I never bothered, and with a Hi-Volume fuel pump on my 440, I haven't had a problem with 5/16. I have a fuel pressure gauge on my dash telling me so.   :naughty:

    Yes, it is accurate. Twice it read zero. Twice I got towed home... Do the math.   :stomp:  My problems were a hole in the fuel line sucking in air, and a crap stock fuel pump.

    NAPA sells brake line in 10 foot lengths, and various diameters.  I made a new fuel line for our Datsun using a simple hand held bender with a round machined hub that has each tube diameter cut into it.  Measure to the mid-corner of each bend on the 'old' tubing, as if there was no radius to the bend. Transfer the measurement to the new tube with felt tip, and place the mark at mid-point of tubing bender, then bend.  Will produce the bend at the correct location.  I had about $10 into tubing and some time.

    I would say go with the pre-bent lines, and just shop around for the best deal.  I would also stick with the 5/16, if that is what you have now.  Otherwise, like said before, you will need a new sending unit.  As far as getting the new lines on, if you have access to a lift it will take you about 10-15 minutes.  If you have to do it on the ground, it might take you up to an hour or so, but with patience it won't be any problems.  Just take a real good look at how the old lines are run, and maybe take some pictures to refer to.

    Already changed them out.  I went ahead and upgraded to 3/8 lines.  I had already upgraded the sender awhile back.  I got both the main fuel line and the vapor line and I got new clips.  All from inline-tube.  All lines were pretty easy to put back on and lined up well, with only the wrap around behind the tire giving me some problems.  Also, the shipping bends are kinda tough to work out, but mainly cuz I was scared to over do it and kink them.  I gotta say it was easier than changing them out on my '71 vette.  Had to lift the body off the frame to change those out.
