SPJIUQI Mechanical Fuel Lift Pump for Big Block Chevy — Edelbrock 1722 Replacement, 110 GPH 6 PSI with Gasket

SPJIUQI Mechanical Fuel Lift Pump for Big Block Chevy provides a high-flow, direct-swap mechanical fuel lift solution delivering 110 GPH at a steady 6 PSI, complete with gasket for Edelbrock 1722 replacements.

This mechanical lift pump is engineered for Big Block Chevy applications (396, 402, 427, 454, 502) and is a drop-in replacement for Edelbrock 1722. It combines a heavy-duty vane/valve layout with corrosion-resistant 3/8" NPT fittings to maintain stable fuel delivery for street, strip, or restoration use. Factory-tested for flow, pressure and sealing, the unit comes pre-assembled and includes the correct gasket set to speed installation and minimize downtime.

How does this pump keep a Big Block Chevy running smoothly under load?

The SPJIUQI pump maintains consistent fuel pressure and ample flow so your engine gets a steady supply even at high RPM. Its internal six-valve arrangement reduces pulsation and prevents delivery drop-off during acceleration, helping avoid hard starts and fuel starvation.

• 110 GPH (416 LPH) free-flow volume rated to support builds up to roughly 600 HP
• Stable 6 PSI working pressure for carbureted Big Block engines
• Six internal valves tuned to minimize pulsation and maintain steady flow
• Polished 3/8" NPT inlet/outlet ports for reliable hose and fitting connections

Will this fit my Edelbrock 1722 or other Big Block Chevy mounts?

Yes — the unit is designed as a direct-replacement, matching the standard mounting hole pattern and port orientation used on many Big Block Chevy setups, including Edelbrock 1722 applications. The kit ships pre-assembled with the correct gasket set to eliminate extra modifications.

• Direct-swap mounting hole pattern for classic Chevy blocks
• Included gasket tailored for Edelbrock 1722-style installations
• No cutting, drilling, or major modification required in most cases
• Pre-assembled body reduces install time and alignment issues

What performance benefits and drivability improvements should I expect?

Expect fewer hard starts, a steadier idle, and reduced risk of high-speed fuel starvation. The pump’s heavy-duty transfer capability prevents power loss under load and helps your carburetor remain properly fed during sustained high RPM runs.

• Eliminates rough idle, stalling, and weak-power symptoms caused by poor feed
• Factory flow-tested to ensure consistent delivery at highway and racing speeds
• Durable internals and corrosion-resistant ports for long service life
• Supports performance builds up to approximately 600 horsepower
