FAQ
WILL THIS FIT MY 1989–1993 FIRST-GEN 5.9L CUMMINS?Yes—this is the OE gasket that seals the VE rotary pump to the gear housing on 1989–1993 5.9L 12-valve Dodge Ram.
DO I NEED SEALANT WITH THIS GASKET?Install dry or as directed by the Cummins service manual. Avoid excess RTV—squeeze-out can affect pump alignment or oil passages.
HOW MANY GASKETS ARE REQUIRED?One per engine (single pump-to-housing interface).
IS THIS GENUINE CUMMINS?Yes—OE Cummins 3939355 for correct thickness and material.
DOES THIS FIT P7100 (’94–’98) OR VP44 (’98.5–’02) TRUCKS?No—those pumps use different mounting gaskets. This part is for VE-equipped engines (’89–’93).
