    I installed a new 3/8 feed line and used the original feed line as a return

    My car didn’t have a factory return line

    Ok, my buddy bought the Sniper system for his SBC powered Jeep Scrambler. I pulled my air cleaner off and the unit fits with some minor mods. EZ enough. The "master kit" comes with the hoses, fittings, electric fuel pump, etc. I'd have to get some angle fittings just for added clearance, no big deal at all. $1259 plus tax from Summit Racing. The instruction sheet is very thin and we wondered where the rest of the instructions were. There is an online PFD file, we missed that on page one. So now everything is good to go. I have tons of reading to do for now, but this spring the Sniper system will be my project. I'll go with the black colored TB opposed to the gold unit. It will control the timing as well, so I have to mod the dizzy to some degree (still reading on that ) Any advantage/disadvantage to going that route? Like I said earlier, I have the 6A box and the MSD billet distributor. As far as I can tell, the fuel pump can go inline, close to the gas tank and high pressure hose going to the engine and a return line which I believe I already have. SO I'm kinda geeked to get it now that I know it will fit. I also get to help my buddy with his first so I wont be going into this totally blind. I'll keep posting with updates in the future. He has a cam change to do first, then the Sniper unit.

    Interesting. So our carbureted cars came with a return line?

    Not all did, my 79 Z-28 does have the return line. The return line was plumed into the fuel pump.

    To that point, I was surprised to see my 81 Z did have the return line. I was wondering if it was because they had the computer controlled carb that year or something else. All that was already ripped out when I got the car other than the line.

    I used the charcoal canister return line, but being that I had a new tank I cut it and put it on the return section of the sender.
    0 issues with 3/8 feed with a 5/16 return

    I went Holley HP for ecm and wiring with my own components for manifold, tb, rails & injectors. I really liked the inputs & outputs and the ability to control nitrous and methanol with it. Everything I've read about Holley has been great. But mine isn't running yet because the car is in pieces.
