• The in-tank fuel pump is a high-pressure 255-lph unit, capable of
supporting EFI engines producing up to 550 horsepower
• The module includes a pre-calibrated fuel-level sending unit that was
designed to work with the factory fuel gauge already in your vehicle
• Holley has included a HydraMat with its unique internal reservoir,
which keeps fuel available at the pickup while also providing protection
from contaminates
• Fuel pressure is regulated internally and preset at 58psi, eliminating
the added expense of purchasing an external fuel pressure regulator
• That is right, this means no return line needed! All return fuel is
handled inside the tank
The Holley 1975-77 Corvette Muscle Car EFI Fuel Pump module was designed
as a direct replacement for your factory pick-up and sending unit.
There is no need for modifications and you will not have to replace your
fuel tank unless you want to. You can even retain the factory fuel hard
line, just connect the outlet of the pump module to the hard line on
your vehicle with some EFI rated fuel hose and hose clamps such as the
Earls Vapor Guard.
Every Muscle Car EFI Module includes a 255 LPH fuel pump and a Holley
HydraMat. The amazing HydraMat is a patent-pending fuel reservoir system
designed to reduce fuel starvation issues present in hard cornering,
acceleration, stopping, inclines, and low fuel conditions.
