Installation Notes and Tips

Verify the tank opening size before installation; this part is intended for 130.0mm cam lock ring applications. Clean the fuel tank before installing a new pump or lock ring, since contamination can shorten fuel pump life. Delphi also notes the use of fuel tank cleaning kit FC01 to reduce contamination risk during service. The gasket or seal is not included, so confirm related sealing components separately.
