Good To Know

Q: How do I know if my selector valve needs replacing? A: Common signs include the engine stalling after a tank switch, fuel gauge readings that do not match the tank in use, or diesel weeping around the valve body. If you cannot draw fuel from one tank, the selector valve assembly is the usual suspect.

Q: Does this valve work on both supply and return lines? A: Yes, the 6-port layout covers supply and return circuits so both lines switch together when you change tanks. Confirm the port arrangement matches your truck's plumbing before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
