The Fleetguard 3845400S Fuel Pre-heater / Strainer Service Kit is a stock-style service kit for the 1994-1998 Dodge Ram 5.9L 12-valve Cummins fuel heater / strainer assembly. This kit includes the fuel strainer screen, 3841883 lock nut, and 3842021 gasket, making it the right choice when you want to service the pre-heater / strainer area instead of replacing unrelated fuel-system parts.

On older 12-valve trucks, the fuel heater / pre-filter area is a known inspection and repair point when you are chasing air in fuel, hard start after sitting, minor seepage, or a fuel-system housing that needs to be refreshed. This kit does not fix every air-in-fuel complaint by itself, but it does let you correctly service the stock heater / strainer assembly in one of the common low-pressure fuel-system trouble spots.

Buy this if:
You have a 1994-1998 5.9L 12-valve Cummins and want to service the stock fuel pre-heater / strainer assembly with the correct strainer, lock nut, and gasket components.

What This Kit Includes

Fuel strainer screen.
3841883 lock nut.
3842021 gasket.

This is sold as Fleetguard / Cummins part number 3845400S, also seen as 3845400-S or 3845400 S.

What Problems This Kit Helps Address

This kit makes the most sense when the stock fuel heater / strainer area needs service because of age, seepage, contamination, or suspected air intrusion around that housing. It is especially relevant if you are trying to keep the factory-style setup intact instead of using a fuel-heater delete.

Service wear in the stock fuel pre-heater / strainer assembly.
Leak or seepage concerns around the lower heater / strainer area.
Air-in-fuel diagnosis where the heater / strainer housing is part of the suspicion.
Routine refresh of the stock fuel-heater hardware during fuel-system service.

Common mistake:
Do not assume this kit fixes every hard-start or air-in-fuel complaint by itself. If the truck still has cracked hoses, loose fittings, drain-back, or weak lift-pump supply, those issues still need to be diagnosed and repaired separately.

Fitment

Fits 1994-1998 Dodge Ram 2500 and 3500 5.9L 12-valve Cummins applications that use the stock fuel pre-heater / strainer setup.

Why This Is The Right Repair For The Correct Truck

If you want to maintain the stock fuel-heater / strainer assembly, this kit gives you the core service parts in one package instead of piecing the repair together. It is the right fit for buyers who want a stock-style repair in the heater / strainer area and do not want to guess on the nut and gasket pieces separately.
