ABOUT THIS PRODUCT

Each module also comes with all the parts and pieces necessary to complete the installation. Included is a 3 x 11-inch Hydramat filter that leverages surface tension to draw from nearly any area that has contact with fuel eliminating starvation under hard acceleration or cornering. Also included is a new fuel pump gasket, wiring pigtails for the level sender and fuel pump, and fittings to connect to the factory quick connect feed and return lines. The modules are all return style, so don't forget to pick up an EFI pressure regulator (such as the 19-392 or 19-395) to complete your installation.
