Magnum and Wiring Swap

Yeah, I figured I should be getting better economy than what it is.
Would you mind posting a pictures of your set up? I'm using whatever pump came with the Tanks Inc kit, I believe a a Walbro and their 3/8" fuel lines. Would an adjustable FPR work? I don't see why it wouldn't.

I was careful to get the smaller pump that supports "only" up to 450 hp. I figured it would be a miracle if I could get a factory Magnum anywhere near 450 hp, so the small pump would be fine. Because with fuel pumps bigger is not better if you don't need it. I've heard a pump that supports way more power than what I have would be working harder for no reason and likely fail a lot sooner.

I think an adjustable regulator would work fine. I didn't use one because I don't run a return line (unless you count the 10 inches from my filter) and I didn't want to put an expensive adjustable regulator under the car near the fuel where it would be abused by dirt and water. I was probably overthinking it, I'm sure it would be fine up near the tank.
