The machined assembly mounts in the factory fuel tank using the OEM ring and gaskets and reuses the OEM fuel level sender. A single -8AN male pump feed port and -6AN male return port simplify aftermarket -AN hose plumbing. The complete assembly fits under the OEM access cover without modification. IMPORTANT NOTES: 1. This system is only compatible with Walbro pumps (Ti Automotive F90000267, F90000274, and F90000285). 2. This system requires the use of an aftermarket fuel pressure regulator. 3. This system eliminates the OEM hanger's "post" fuel pump filter. A low micron aftermarket fuel filter should be installed downstream to protect the injectors from contaminants.
