1997-2003 C5 Corvette (Will work for 2003 Corvette's built before October 2002)
The Racetronix PnP upgrade harness provides alternator direct power for maximum pump voltage. Racetronix has documented an
average 1.2-1.5V increase in pump voltage in the C5 which equates to a 15-18% increase in pump volume based on Walbro's
specifications and Racetronix field tests. A minor increase in fuel pressure will actually be experienced with the installation of this
harness. The harness is fully 'plug and play' and is installed without cutting into factory wiring. The entire harness is weatherproof
made with the same Delphi interconnect components used throughout your C5. The harness' operation is quite simple. The factory
power wire which was once used to power the fuel pump is used to trigger a 40 amp-rated relay which in turn supplies
power directly from the alternator with fused protection. |
