Review on NMN Precision Electric Vacuum Pump 6C3Z2A451A for Ford F250, F350, F450 Super Duty - Compatible with 6.0L, 7.3L, 6.4L Engines, 2003-2004 Models - Replaces 6C3Z-2A451-A, 904-214 by Payton Luna

Looks good, but I have a wire that has come loose. I bypassed the vacuum controller but the unit only drew 12 to 15 on my gauge. I don't know the specifications of the car system. This does not evacuate the AC system! I use it as a switchable vacuum source to bleed the brakes. My hands are tired from vacuuming with a hand pump! Runs great on a 12 volt, 7 amp rechargeable battery. There are no wires or connectors, but pins from a computer wiring harness were used. Grumpy46
