❓ FAQ

Both numbers are listed for this cover cap, with AB the later revision. If the cap on your housing reads 68436815AA, this one replaces it.

Yes. The 2020-2023 Ram 1500 3.0L diesel is on the list, together with the 2019-2024 Ram 2500 to 5500 6.7L Cummins. Petrol Ram 1500 trucks use a different cap.

Usually the O-ring has hardened or the cap has been over-tightened until the seal groove distorted. Fit a new cap and tighten it by hand to the point where it stops, not beyond.

No. The pack holds the cover cap only, and the separator element 68436631AA that sits inside the same housing is a separate part. Order both if you are servicing the housing.

Hand tight is enough on a cap with an O-ring seal — the seal does the work, not the torque. A wrench on a plastic cap is how the thread and the groove get damaged.

Description

Product Overview

68436815AB is the cover cap that closes the frame-mounted diesel fuel filter housing on 2019-2024 Ram 2500, 3500, 4500 and 5500 trucks with the 6.7L Cummins, and on the 2020-2023 Ram 1500 3.0L diesel. It screws onto the housing, seals the fuel inside and holds system pressure at the filter head.

Key Features

Closes the housing properly — a cap that no longer seals lets diesel weep past the threads, drops system pressure and leaves a smell of fuel around the frame rail.
Moulded thread, no stripping — the thread is formed in the same nylon and plastic body, so it engages the housing without the galling an aluminium cap can bring.
O-ring seat kept square — the seal sits in a machined groove rather than being pinched against a flat face, which is where most reused caps start leaking.
Matte black finish — matches the housing it sits on and does not show the road grime the way a bright cap does.
One cap, routine filter changes — the cap comes off and goes back on at every element change, so a spare in the toolbox ends the waiting when one cracks.
