Review on WIX Filters 51551: Highly Durable Spin-On Hydraulic Filter [1-Pack] - Effective Filtration System by Paul Green

I bought this to replace the Baldwin BT839-10 in my MotorVac because the filter was never changed. When I installed it the gas was not flowing in the right direction and when I removed it the gas in the filter was under pressure even though it had theoretically released all the pressure. After installing the native filter, everything worked. This filter has been listed by WIX as a direct replacement.
