Brand new direct replacement vacuum pump for all 92-95 6.5TD vans.
Your vacuum pump controls your turbo, and on Light duty trucks the EGR valve also. If you are experiencing turbo problems, it may just be low vacuum. Vacuum should be a minimum of 15 inches of vacuum at the wastegate valve to operate properly. Preferably 25+ inches of vacuum. Anything less then 15 and your boost will be low and you may trip a code with your ses light. This pump is belt driven off of your serpentine belt.
Also fits 88-92 vans with 6.2's using the serpentine belt driven vacuum pump.
