Dorman - OE Solutions Vacuum Pump P/N:904-821
Keep the vacuum-powered systems on your Ford truck or van supplied with the Dorman - OE Solutions Vacuum Pump 904-799, a pre-assembled pump-and-pulley unit that drops in as a direct replacement on the listed Ford Econoline vans and Super Duty trucks. The original equipment vacuum pump on these vehicles tends to fail when the pump shaft unthreads, loosens and separates from the pulley — and the dealer sells the pump and pulley as two separate pieces that need special tools to assemble. This all-in-one assembly ships ready to install, so you skip that headache.

This part cross-references / interchanges with the following part numbers:
What does this vacuum pump do?
It generates the vacuum used by vacuum-operated systems on the vehicle. If the original pump has failed, this unit replaces it to restore that vacuum supply.
Does it come pre-assembled?
Yes. The pulley and pump ship pre-assembled with necessary hardware included, so you don't need repair-specific special tools to put them together.
How is this different from the factory pump?
It features a welded-on pump shaft end to help keep the pulley from separating from the pump — the failure mode where the factory shaft unthreads and loosens.
Will it fit my vehicle?
It's a direct replacement for the listed Ford Econoline vans and Super Duty trucks. Check the Buyer's Guide tab to confirm your year, make, model and engine.
What numbers does it replace?
It interchanges with 273-10378, AP63700, EGR415, F6TZ2A451AA, ETS74 and VCP120. Match one of these or your vehicle in the Buyer's Guide to confirm.
