Re: Help with fuel system design for LS1 install

Re: Help with fuel system design for LS1 install
if ive got a 99 lm7 5.3 motor which has a feed and return built into the motor do i have to run the return all the way from my fuel rail back to the tank(leaving 1 port open on the regulator) or can i run in back to the regulator(3 ports used) and just have the feed come from the tank????
read this whole thing and have not found and answer yet.

Re: Help with fuel system design for LS1 install
^ What he said.
The C5 filter / regulator is NOT the part you want when using the return-line style engines. That is for the second run of LS stuff with the "returnless" fuel rails. I used an LS1 Camaro fuel filter with my return-line type LS swap. Annoying to plumb without resorting to AN fittings but it can be done cheap and, I'm sure, with AN it's easy.

Re: Help with fuel system design for LS1 install
Based on all the reading here, here is the plan I came up with to route fuel from a Boyd tank with intank fuel pump. Did I miss anything? Is 25 feet enough or too much? Fuel tank is mounted under the bed.

Re: Help with fuel system design for LS1 install
Depends which rails you have, return style or returnless. If you have returnless rails that will do it but I would look at using OEM type nylon fuel line & connectors to save a boat load of money over going all AN stuff.

Re: Help with fuel system design for LS1 install
Thanks for the response, that is a great idea. Mine is a return-less, and I did a little digging. Unfortunately I could not find a -6orb to 3/8 SAE Quick disconnect, so I had to use a combination of connectors coming out of the pump. Even with that, this is a significant savings.

Re: Help with fuel system design for LS1 install
Very interesting thread, following.
Like your system BR3W City, you think you have part numbers for some of those fittings, and stuff you used? |
