Will this setup work?

[Krazykid]

Well I have received my PPE Lift pump from McRat Racing the other day and I'm working on the installation pieces. I have attached a very crude drawing of what i have in mind. If I splice into the 1/2" Fuel line on the frame rail with a couple of T's, I was planning on mounting the PPE Lift pump inverted on the brace between frame rails just in front of the Fuel Cooler. Now the T's are for a pump bypass, as I only plan on running the pump at the track or while using a race tune. Please let me know if you see any problems with this idea?

you need a check valve in there.

this might help you if you dont need to run a return line Im not familiar with the kennedy pump.

This should help!

What is this check Valve? (i'm assuming the same thing as a diode?) And I'm guessing the mounting location and position are fine? Also the way I was planning on plumbing the T's, any issues?

RPM, your picture is what I started with NICE job, just to rich for my blood.

yor gonna need a check valve ( Brass piece on top in RPMs pic) or a flapper of some kind so when the pump is on it wont short cycle the fuel around itself and sends it to the motor

also if the pump fails on you the check vlv will open and allow fuel to by-pase the failed pump

Thanks guys......Can a 1/2" check valve be had at Lowes or home depot?

 

[duramax3388]

i had a really hard time finding one and i had to go to a specialty plumbing store to get it no one else in town had anything close to it. lowes had one that was an inch and a quarter but that thing was about 3in. around dont think thats going to work.

there is no pressure but will leak alot of fuel so have some pans ready .

When I cut the line, I used my air gun and shot the fuel back into the tank. It made it stop pouring all over the place.

i got a 1/2" ball valve in mine that keep ~60gl at bay :baby:

I like the idea of using the airgun to shot the fuel back into the tank. How much fuel can i expect to leak out when cutting in? 1 gallon, 5 gallons whats a lot of fuel? Going to cut the line tomorrow, just finished all the relay wiring through a switch in the Socal gauge mount, everything is working out so far. Hope to have this finished before Thrusday.........Race day! Thanks for everyones help and advice.

 

[RPM Motorsports]

about a cup from the engine side, but the tanks side might keep siphoning if the line is not blown back!

 

[maxaholic]

If you blow it back with a airgun be sure and take the fuel cap off. When I did mine I actually pressurized my tank and fuel kept coming out of the line.
