• Noise or wear associated with an aging in-tank pump module

Installation Notes and Tips

Verify vehicle fitment by year and model before installation. This module is designed for in-tank use and includes a seal, but mounting hardware and lock ring are not included. Confirm connector shape, terminal count, outlet style, and fuel line routing against the original assembly before removal.

For best results, inspect the fuel tank for contamination and replace any damaged lines or connectors during service. The module uses a 12-volt electric pump with a 5-terminal pin connection and is intended for gasoline systems only.
