Pump Only vs Fuel Pump Assembly

Option	Description
Replace Pump Only	Lower parts cost but requires disassembling the existing module and reusing older components.

Most modern vehicles use integrated fuel pump modules, which makes replacing the full assembly the more reliable solution.

Q: Which vehicles use the E7187M module?

A: It covers selected 1998–2004 Dodge Ram 2500 and 3500 trucks with the 5.9L Cummins diesel.

Q: Why must 2003–2004 trucks be inspected before ordering?

A: Those trucks may retain an engine-mounted transfer pump or may have been converted to an in-tank supply pump.

Q: How can the conversion status be identified?

A: Inspect the rear of the fuel filter on the driver side of the engine for the transfer pump, block-off plate or conversion tube.

Q: Is this module interchangeable with an unconverted engine-mounted pump system?

A: No. The fuel supply layout and wiring must match the installed configuration.

Q: Is the fuel-level sending unit included?

A: The sender package must be compared with the product and removed module before installation.

Q: Which OE numbers should be checked?

A: Compare 4897668AC or AF, 5174262AB, 5179873AB or RL179873AB.

Q: What should be tested before replacement?

A: Test low-pressure supply, voltage and ground, wiring, relay operation, restrictions, air intrusion and sender continuity.

Q: Can E7187M be used for a gasoline Ram?

A: No. It is associated with selected 5.9L Cummins diesel fuel-system configurations.

Q: What should be inspected while the tank is removed?

A: Inspect tank contamination, wiring, connector, supply line, seal surface and lock ring.

Q: What checks are required after installation?

A: Prime the diesel supply system, inspect for leaks or air intrusion, verify supply pressure and confirm gauge operation.
