1990-1996 C4 Corvette Fuel Pump - Performance 340LPH

• OSIAS 340LPH turbine fuel pump with reduced noise and enhanced reliability with ethanol- enhanced fuels
• Filter sock - 30 micron filtering (factory=70 micron)
• Direct hookup heavy-duty Teflon harness - no adapters, E85 compatible
• Stainless FI gear clamps
• Pump mount grommet
• Pump sound insulation sleeve
• C4 fuel tank gasket
• o-ring seals 

Our 340L/Hr high-performance fuel pump is capable of supporting approximately 550RWHP* @ 13.5V @ 43.5PSI through factory lines when installed in combination with our upgrade harness. Many C4 Corvettes have bulkhead connectors which are in very poor condition. 

OSIAS 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. OSIAS 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。 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. Most C4 tank gaskets are in pretty bad shape and will not provide a proper vapor seal. 

In-tank Wiring - OSIAS 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.

OSIAS in-house harness manufacturing facility has produced a one-piece replacement for the in-tank pump wiring. OSIAS 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 OSIAS 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.
