I was looking at aero motives fuel pump wiring upgrade and was wondering If need it. Also $70 seems alittle steep for a relay and some wiring. Can I make this kit with parts from the auto parts store and wire it in? The aero part number I'm looking at is Jegs number 027-16301. I plan on runny my 255 pump with a inline pump like the t-Rex or the Aeromotive stealth in tank pump, on my turbo set up. Any help would be appreciated.

Do not try to wire the fuel pump without the relay. The 15-20 amps the pump pulls will overload the circuit. This will take power away from other items on the same circuit or cause the fuse or fuse link to blow.

I think I will run the aero, I hear doing the wiring upgrade help with even just running a in tank pump. Is that wrong?
The existing wiring is good for 20 amps. Check the current draw spec for the pump you plan on using. If it is 20 amps or less, you probably won't gain any measurable increase in flow by replacing the wiring. The fuel pressure regulator limits the fuel pressure, so you won't gain anything there without adding a FMU.

Thanks I'm still undecided on which route I want to go but I think a new in rank pump would be easiest
