Reliable replacement pump
Verified Buyer -
Perfect fit, and a good brand. Never had an issue with these pumps
I would buy this pump again.
Verified Buyer -
I replaced my oil pump because it no longer held a press fit with the oil screen. The combination of the pump and screen restored the oil pressure to where it should have been.
