    The previous owner set this car up with both mechanical and electric fuel pumps (electric being on a manual switch). I will definately be doing some re-plumbing for safety reasons, as well as looks. How have some of you done the plumbing?

    Here's a description of mine:

    -Electric leg: bottom feed from stock tank to filter to pump to check valve to regulator inlet. (1/2" from outlet of filter onward)

    -Mechanical leg: stock line from tank to FP to one outlet side of the regulator (un-regulated, I suppose, as it bypasses it)

    -Combined leg: Other outlet side of regulator will then see un-regulated mech flow but regulated electric flow. This then goes to an in-line filter to local gauge to dual feed lines to a Speed Demon carb (I'm assuming there are filter screens there too??). Then at the end of the dual line is a return to the tank (Do I need a return?).

    Sorry if this is too many questions in one post.:laugh:
