When switching your 1978-1988 Buick/Chevrolet/Oldsmobile/Pontiac G-Body to EFI, you will not find an easier way to upgrade your fuel system than our OE Style 350 LPH EFI Fuel Pump Modules. They are a direct replacement that fits your factory fuel tank so you don't have to guess when it comes to something as important to your project as the fuel system. Because it was designed as a direct replacement for your factory pick-up and sending unit, there is no need to purchase a custom EFI fuel tank. You can even retain your factory fuel line. Simply 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 Earl's Vapor Guard Line. Regulator and HydraMat filter are also available for purchase.

  • Includes a pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for your application
  • Solves all the usual issues of converting from carburetor to EFI
