Holley 255 LPH OE Style EFI Fuel Tank Modules 12-301

Fuel pump module in-tank for Chevrolet Camaro & Pontiac Firebird.

This high-pressure unit flows 255 liters per hour (LPH) and supports electronic fuel injection (EFI) engines producing up to 550 horsepower.

Included is a pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for this application.

The module features a HydraMat filter with a unique internal reservoir that keeps fuel available at the pick-up and protects from contaminants.

Fuel pressure is internally regulated to 58 psi, eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator - no separate return line is required because this module returns excess fuel right inside the tank!

Designed as a direct replacement for your factory pick-up and sending unit, this 1970-73 Camaro/Firebird Muscle Car EFI Fuel Pump module does not require a custom EFI fuel tank.

You can retain the factory fuel hard line - just connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line.

This Muscle Car EFI Module includes a 255 LPH fuel pump and a Holley HydraMat.

HydraMat is a patent-pending fuel reservoir system that reduces fuel starvation issues that might occur while cornering, accelerating, stopping, traversing inclines, and during low fuel conditions.

If your car was equipped with the SBC (305 and 350) engine, the fuel line was routed up the passenger side of the chassis like our 12-304 is designed.

(SBC or BBC fuel pump on passenger side of the engine.

Just like Camaro with SBC or BBC) If your car was built from the factory with the Pontiac or Oldsmobile engine (mechanical fuel pump is on the drivers side of engine), they ran the factory fuel line up the drivers side of the chassis.
