Tired of plastic caps that round off and need replacement?
Dress up your engine with a beautiful anodized aluminum cap that should last forever!

Need to measure fuel pressure?
This cap makes it easy! In the center of the cap, you will find an 1/8 NPT (pipe thread) fitting to which you can easily attach a standard fuel pressure gauge. Attaching a gauge at the top of the filter is much easier than at the factory test port which requires a custom adapter and has a number of obstructions preventing easy access. The pressure test port comes with an allen pipe plug in place - easily removed whenever you wish to measure fuel pressure. Do not under-estimate the importance of checking fuel pressure on a 6.0L diesel! Low fuel pressure is a leading cause of premature injector failure.

Available in silver, or red to brighten your engine compartment - select color below.

Note: We also offer this cap with a 1/4 Schrader valve in place to make connecting any standard fuel pressure gauge even easier - add the Schrader valve option below when ordering.
