Verify the vehicle’s fuel system layout before installation, especially the 3 line pump configuration noted for certain Pontiac applications. Confirm the part number 530-8085 against the original pump and compare mounting, line routing, and engine application before service. Because no gasket is required and a strainer is not required, follow the vehicle’s service procedure and inspect related fuel lines and connections during replacement.
