Dorman 904-799 Vacuum Pump Assembly With Pulley
Features:
- Improved design – to prevent the pulley from separating from the pump, this all-in-one vacuum pump features a welded-on pump shaft end to help ensure a more reliable and longer-lasting repair
- Simplified installation – eliminates the need to source and use repair-specific special tools
- Direct replacement – engineered to exacting specifications to match the performance of the original equipment vacuum pump assembly
The original equipment vacuum pump on certain Ford Econoline vans and Super Duty trucks tends to fail when the pump shaft unthreads, loosens and separates from the pulley. Replacing a pump with another failure-prone factory unit can also be a hassle because the dealer only sells the pump and pulley as two separate components that require special tools to assemble and install. This Dorman OE FIX vacuum pump is pre-assembled, reducing labor time and eliminating the need for repair-specific tools for a complete and professional installation. And, to prevent the pulley from separating from the pump, this all-in-one vacuum pump features a welded-on pump shaft end, an important upgrade engineered to help ensure a more reliable and longer-lasting repair.
