Holley/MSD has announced the release of Holley Diecast Retrofit Fuel Pump Modules, which support up to 875 EFI horsepower or 1,100 carbureted horsepower and make it easy to affordably upgrade to EFI. Available in return and returnless versions, they convert your factory tank or fuel cell to an in-tank EFI fuel system and provide all the benefits of HydraMat technology. They're easy to install with basic hand tools and require no welding or fabrication whatsoever.
Holley Diecast Retrofit Fuel Pump Modules include a diecast pump-hanger bracket to control pump vibration in a low-profile design that's perfect wherever space is at a premium. They fit any fuel-tank depth from 7 to 12 inches and protrude only 1.275-inch above the tank-mounting surface to accommodate numerous applications. You can locate the module beside your existing sending unit anywhere in the tank and rotate it a full 360 degrees to work flawlessly with various plumbing and wiring configurations. The innovative HydraMat system ensures a steady, consistent fuel supply, and its 3x15-inch mounting flange has six different clocking-pin locations to allow for 360-degree adjustment to clear sending-unit levels and any tank-floor restrictions. Once the module is installed, all you need to do is connect your power-source/ground and fuel lines.
