Xtreme HD Fuel pump for the 97-03 C5/Z06 Corvette. Supports up to 650 hp. Racetronix has upgraded the factory Teflon wiring from 16 gauge to 14 gauge silver-plated multi-strand copper wire. This helps reduce voltage drop and at the same time maintains the same level of resistance to fuel solvents as the factory wiring. Generic Walbro kits do not use Teflon wire but rather a much less expensive plastic type. The Racetronix in-tank wiring harness is a one-piece assembly. One end has the Walbro connector and the other is fitted with GM type terminals which are installed directly into the factory connector making it true plug & play. Generic wiring harnesses require cutting and splicing of the factory wiring. Note that this fuel pump will only work in the C5/Z06 Corvette manufactured prior to 11/27/02. !!NEW!!The wiring harness is also available by itself for '03-1/2-04 cars as a plug and play unit for hooking up a boost-a-pump. No pump is currently available for these models. The wiring harness will help take the load off of the stock wiring, which can be damaged due to the extra voltage.
