Our 255L/Hr high-performance fuel pump is capable of supporting approximately 550RWHP* @ 13.5V @ 43.5PSI through factory lines when installed in combination with our FPWH-013 upgrade harness. Many C4 Corvettes have bulkhead connectors which are in very poor condition. We highly recommend that they be replaced with our BCWA-C43 wiring assembly to prevent wiring and pump failure as well as potential motor damage.

NOTE: We have had many customers indicate that the hanger wiring in their cars is not compatible with our in-tank harness. This is because in some cases GM used random leftover inventory. Unless you are able to pull out your hanger and confirm that you have the C43-type in-tank harness and that it is in good condition we strongly recommend purchasing the BCWA-C43 noted above. Pending review, this may become a mandatory purchase due to the poor condition and varying types of early C4 hangers.

HP numbers will vary based on engine and driveline efficiency, operating pressure and pump voltage.

Pump Installation kit- Racetronix Exclusive!

Racetronix manufactures this kit specifically for the C4 Corvette. Walbro's 400-1016 fuel pump installation kits which are normally bundled with the F20000169 pumps are tailored towards 1980's g-body and b-body fuel senders. Racetronix has bundled together a C4 specific fuel pump installation kit which includes a few upgrades such as a sound insulation sleeve, one-piece teflon in-tank wiring harness, C4 tank gasket and stainless sender bolts with o-rings. The factory pump came with a sound insulation sleeve so we have included one. This sleeve helps reduce pump noise heard from outside the tank. Racetronix has manufactured a quality C4 tank gasket and bundled it with new stainless steel tank bolts and o-rings. Most C4 tank gaskets are in pretty bad shape and will not provide a proper vapor seal. The factory black-oxide sender bolts are typically rusted and their o-rings have deteriorated. These bolts must be in good condition and their o-rings intact to achieve a vapor seal as they extend into the gas tank. GM fuel sender gasket (P/N 25091503) lists at $15.25. The fuel sender bolts with o-rings (P/N 14044556) list at $45.54 for a set of nine. A total value of $60.79 included at no extra charge. Racetronix supplied bolts and tank gasket are made from superior materials. A hex key is included to aid in the installation of the stainless sender bolts.

In-tank Wiring - Racetronix Exclusive!

In-tank wiring is quickly becoming a major problem due to the age of the C4's. Many terminals are heavily corroded or rusting off.
The generic in-tank wiring adapters supplied with other installation kits rely on the questionable factory wiring and adds another connection to the equation. This translates to more resistance / voltage loss and an extra potential failure point.

Racetronix in-house harness manufacturing facility has produced a one-piece replacement for the in-tank pump wiring. Racetronix replacement in-tank wiring plugs directly into the new pump and into the factory bulkhead connector thereby eliminating all the factory pump wiring and the need for in-line plug adapters. The Racetronix harness is made with heavier 14 gauge Teflon wire vs. the factory's 16 gauge wire. Teflon is the most resistant to gas and solvents. All connections are assembled using our computerized crimp-quality monitoring system and then circuit checked for the utmost in reliability. There are no wires to cut, crimp or splice.
