Quantum 255LPH In-Tank Fuel Pump for Nissan 300zx 1984-1996

Looking for a quieter, more reliable alternative to loud and expensive Walbro in-tank pumps? The Quantum 255LPH High-Pressure Fuel Pump delivers proven reliability, verified by RC Engineering, and is backed by a Lifetime Warranty — a rare commitment in the performance fuel-pump industry.

This universal, high-performance fuel pump provides a flow rate of 255 LPH at 43.5 PSI with a low 9.45 Amp draw. The pump measures 123.5 mm in length × 39.3 mm in diameter for drop-in installation in most fuel systems.

A key advantage over Walbro pumps is the higher-PSI bypass valve, making it ideal for turbocharged and supercharged applications that demand consistent fuel pressure. Its advanced vane-impeller design ensures quieter operation — producing only a faint “wheen” sound during priming and running virtually silent once the engine is on.

Don’t risk failure with old parts — this complete kit includes the pump, strainer, fuel hose, hose clamps, wiring harness, foam sleeve, and rubber boot, providing all the necessary components for a proper installation.

Engineered for consistent pressure and flow under high-demand conditions, the Quantum 255LPH helps maintain peak engine performance and long-term durability. Its compact size makes it ideal for custom builds, race cars, and street-performance vehicles. Dimensions are provided to confirm OE module fitment (minor modifications or fabrication may be required).
