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.
