Question on booster pump install
I'm about to do the in-tank mod with remote filter and booster pump. My question is will the existing circuit that runs the OEM pressure pump be able to handle the addtional 4.5 amps tied to it or should I run a relay off of that circuit with a dedicated feed to the booster. If I run off the existing circuit should I increase the amp rating 5amps?

You don't want to do that. The OE pump circuit is rated for the wire size. If you add an additional 5 amp draw and put a higher amp fuse in the circuit you stand a good chance of overheating the wires. You also may not get all the power you want to the OE pump.
You're going to want to use a relay to run your lifter pump. Use the OE circuit to activate the relay, I just used a ring terminal on the + of the OE pump and a length of wire to the relay to activate it. That way they both turn on and off at the same time.

I guess my question is why do you think you need a lift pump? Stock system handles 500+ HP. All I have is the in-tank mods & RR on mine with stock pump. It feeds my hybrids just fine. Not trying to be a smartass here- that is really complicating your fuel system for no reason. Unless you're planning on building a monster PSD, that is.

Just thinking about removing the strain from the OEM pump pulling thru the pre-filter. Thought of increasing it's life. But if everybodys in agreement that it's not needed, I'm all for leaving it out.

Man, they last for years & hundreds of thousands of miles. I *may* put in a Walbro GLS392 after I get all my other mods done, but seriously -- once you do the pre-pump & RR mods, the stock pump will keep enough pressure on stock sticks for sure, and even up to good size hybrids like mine.
What kind of pre-pump filter are you running?

FWIW, I'm pulling power for lift pump right from the battery. It's just easier that way to go from there and put a fuse or circuit breaker in line.
I used this pump:

And this harness:

You can make your harness if you want, but it's nice to just use that one.

My heavily modded fuel system has the stock fuel pump relocated so that it is pulling veggie oil through a 5 micron filter. It has lasted 28,000 miles and counting. I figure if it pulls veggie oil through a 5 micron filter, pulling diesel through a 2 micron should be no problem.

So far it's just fine. I was concerned with the lack of a diesel endorsement too. They do have a marine pump just like it with the same specs that says good with diesel. But when I called Federal Mogul they said it would be ok. So I went the cheaper route, if it does fail because of diesel use I'll use the marine version. I figured if he said it was ok and also good with race gas, alcohol, gasohol, etc it should be fine for diesel.

The first pump lasted 200k + miles, I'd like the second one last as long if not longer. I know there's no guaranty, it could die tomorrow but I'd like to give it a fighting chance. My primary consern is keeping air out, reducing injector noise, increasing injector life, and of course try to improve mpg and hp.
