Holley is pleased to announce the expansion of its already extensive line of EFI Pump Modules to include three new models – one for 1970-86 Jeep® CJs, one for 1978-87 GM G-Bodies, and one for 1973-87 GM C/K Series trucks. All three are capable of supporting up to 550 horsepower, and all make it simple to upgrade your carbureted fuel system to EFI. As direct replacement factory pick-ups and sending units, these modules come with a 255-pound-per-hour in-tank fuel pump and a HydraMat fuel reservoir, which keeps fuel available at the pickup and reduces starvation during cornering, acceleration, stopping, and anytime the tank is low.

Holley EFI Pump Modules don't require a whole new tank or any fabrication or modifications to the one already in your vehicle. You can even retain the stock fuel hardline – all fuel return is handled right inside the tank. Fuel pressure is preset at 58psi and regulated internally, which eliminates the unnecessary added expense of an external pressure regulator. This module even includes a fuel-level sending unit pre-calibrated to work with the existing factory fuel gauge.
