Installation Notes and Tips

Confirm the vehicle uses a return line and 3-line pump configuration before installation. Verify inlet and outlet connection styles, including the 0.375 in. hose bead inlet and 1/2-20 UNF threaded outlet, against the original pump. Clean the mounting surface thoroughly, replace the gasket during service, and follow the included instruction sheet for proper installation and priming procedures.
