Thank you in advance anyone who can help.
Hi take your engine serial number which is usually on the top of the valve cover assembly, usually MH have access to the top of the engine through a floor hatch in the rear. Then call cummins service line at 800-286-6467 or go to their website https://www.cummins.com.customer-assistance
there you can send in a question and they'll answer you within 24 hrs. Anytime I've called they've been very helpful. Write down any other questions you might have everytime I've called not only have they answered many of my questions like filter part numbers but capacities, etc. . Let us know how you've made out.
