Thread: Fuel Line Plumbing

  1. #1

    Default Fuel Line Plumbing

    I'm about to install the Sniper in my '69 Ford Mustang. I'm going to use an in-tank fuel pump and had some installation questions.
    1. Can I use the stock metal fuel line as one of the lines to the Sniper EFI? I'm pretty sure it is a 3/8" steel line, and I was hoping to plumb it into the system.
    2. If I were to use the Holley PART# 12-876 fuel regulator back at the tank, could I just run a short return from the regulator to the tank,
    and then just have the one regulated fuel supply line running from the regulator to the Sniper EFI?
    Thanks, Kevin

    Yes, if it's 3/8" fuel line.

    Yes, that's the idea.

    Thank you for the information. One more quick question. Looking at the instructions, they identify the correct hole to use for the GM transmission. Which one should I use for the Ford AOD?

    I also have the Ford AOD (Lentech Strip Terminator AOD). Use the hole that pulls the TV cable out all the way at WOT.

    I had not seen these Holley all in one regulator filters before reading this thread, thanks.
    What do you do with the regulator & return fitting on the Sniper EFI, if you implement this setup?

    Install a -6AN Cap (LINK) on the Sniper fuel pressure regulator return fitting.

    It's been discussed on this forum before. It's not a good idea for every application:

    What would you consider an inappropriate application?

    The run from the fuel tank to the throttle body on my car, is about 6 feet or so. My car uses a fuel tank from an '87-'93 Ford Mustang and is plumbed utilizing a drag sump & return line with an inline pump. I'm presently assembling parts (new stock EFI tank) to convert to an in tank setup with a 255 LPH Walbro pump and high flow pump hanger with 3/8" feed & return. Any problems with this?
