    Well after this crazy busy summer, I'm about to order the Sniper. Did tons of research and changed out a few items that I will order. Going with just the efi unit and the gas tank from Holley that comes with an in tank pump and a fuel level sender. The fuel line kit(s) are for 1 line or 2-return style--- Watched a lot of videos but cant seem to make up my mind if I want a return line or not. Any advantages or disadvantages to either?

    I went with the Holley 12-304 pump, has built in pressure regulator and return. I'm using this with an Eddy ProFlo 4, no issues. Holley Sniper forum should have some info on this.

    I just put a Sniper EFI on and did the return line. It was super easy, I just ordered a new pre bent hard line, and just laid it right next to the existing. The old supply became the return. It was the least fun part of the entire swap, but if you do it right the first time, you only have to do it once.

    I was thinking the return line was the way to go also. How's the car running?

    if you are running a Poncho motor ....you can use the existing return line as the return. It is coming from the passenger side and crosses at the front crossmember. IIRC i simply cut it on the pass side and using braided line went up the front of the motor on the pass side to my regulator (which is mounted on my intake...after all injectors) but my system in an older Commander.

    No poncho motor. My items should be here today or tomorrow. Bought the kit for a return line ( 40 feet of hose) The 20 foot kit requires an adapter for return-less for $70, so it pretty much a wash price wise.
