FAQ

What is the 901-04-0004-4?

It adds a warning light that illuminates when pressure at its sensor falls below 5 psi. It is a threshold warning system, not a continuous pressure gauge or a substitute for the pumps application-specific pressure requirement.

What application does this version fit?

Universal diesel fuel-pressure warning installation with compatible sensor plumbing and electrical connections. The 5-psi trigger must suit the system being monitored.

What is included with this listing?

Wiring harness; Indicator light and face plate; 45-degree elbow adapter; 5-psi pressure switch; Grommet.

Does this replace every similar-looking component?

No. Match the products function, connections and complete system configuration; appearance alone does not establish compatibility.

How should pressure or electrical setup be selected?

Use the verified ranges and connections above, then follow the exact guide. A warning threshold, regulator range and engine operating pressure are different specifications.

What should be checked before installation?

Check the installation location, connections, required tools and supplied components against the exact guide. Do not adapt a different vehicle kit solely because the pump looks similar.

Are additional parts supplied automatically?

No. A gauge, sender, additional fittings, separate regulator or complete fuel system is included only when expressly named in Whats Included.

What should be checked before driving?

Follow the priming and startup procedure, inspect every fuel and electrical connection, verify pressure with appropriate equipment, and check for leakage and hose abrasion.

Installation Instructions

1. Choose a pressure sensing point and mounting location consistent with the manufacturer diagram.
2. Install the supplied pressure switch and adapter without contaminating the fuel line.
3. Route and connect the light wiring using the diagram, protecting it from heat and abrasion.
4. Test the warning circuit and inspect the sensor connection for leaks.
