Vacuum Pump ModEffective dehydration prior to charging a system with refrigerant takes valuable time and time is money. As a manufacture of high vacuum pumps for over 40 years we find many problems experienced in the field are due to misunderstanding of vacuum principles.

This will only pull a vacuum on the vacuum hose and micron gauge. The micron gauge should register a micron level in a relatively short amount of time. If it doesn't, there is a problem with the micron gauge, vacuum pump, or interconnecting hose.

So aside from the shorter wires and the Subaru part numbers, this seems to be an exact fit. The original pump even says UP on it as well as being manufactured by Hella, too. Now the fact that the original pump failed is probably more related to the pump being spec'ed too low only for hours for brake booster duty on a car driven in a lot of traffic.
Research led to discovering the aux vacuum pump has failed The oem part is a Hella rebranded Subaru part with "UP28" on it's part sticker. The Amazon part details specified "EP28" which may be a typing error since once I received this part it had "UP28" on it's part sticker. After replacing the part, the erbb error code never returned.
