Hello,
I have a hard time choosing new oil pump for my 3.1 v6 1991 camaro.
Numbers on my pump are 154, GM3177, 148, and 10118839 - that one could be 10118639

The standard volume / pressure pumps I find on rockauto are
MELLINGM134
Alternate/OEM Part Number(s): 10118640, 10229785, 10229787, 12593581, 8101186400, 89060444

ENGINETECHEP134



or even better if I could just buy rebulid kit for my pump:
SEALED POWER22451317
Use To Repair 224-4148 and 224-4152 Oil Pumps

MELLING K95B
Use To Repair M-95, M-95B, M134 Oil Pumps


The problem is that all producs are looking the same to me from the pictures, I`m not sure if everything would fit or not.
Also where does the white plastic bushing goes? I dont have that piece on my pump...


Thank you for anwsers

 

Some oil pump shafts have a slit were that little white piece goes. Mine didn't. You can buy one with a slit. Helps keep the shaft from coming up out the oil pump. . Might as well get a new one as they wear.

 

Thank you for anwser... I still don`t know if I can install any of mentioned oil pumps, do you know anything about this?

 

The Melling pump is a good quality pump/ rebuild kit. You can check part numbers for your vehicle on their website, or just give them a call. https://www.melling.com/

 

I will take their M134 pump 👌
