FAQ

Common Questions

How do I know if this solenoid fits my Cummins engine?

This 12V solenoid fits Cummins C & B series engines (5.9L and 8.3L). Commonly found in Dodge Ram trucks, construction equipment, and industrial applications. Verify your part number matches 3919422, SA-4026-12, or any of the cross-reference numbers listed. Important: Confirm your system is 12V (not 24V). Call (818) 261-3896 if you need help verifying compatibility.

What does a fuel shutoff solenoid do?

The fuel shutoff solenoid controls fuel flow to the injection pump. When you turn the ignition key on, the solenoid energizes and allows fuel to reach the engine. When you turn the key off, it de-energizes and stops fuel flow to shut down the engine. It’s an essential safety component that prevents engine run-on and controls starting/stopping.

Can I install this solenoid myself?

Yes, if you have basic mechanical and electrical skills. Installation involves disconnecting the old solenoid, removing mounting bolts, installing the new unit, and reconnecting wires. Make sure connections are tight and properly sealed to prevent fuel leaks. If you’re not comfortable working with fuel systems and electrical components, have a diesel technician install it.

What's your return policy

We offer free returns within 30 days if the part doesn't fit or you're not satisfied. Parts must be unused and in original packaging.

Do you offer technical support?
