    Chevy Melling M55 oil pump

    Melling oil pumps are the best in the business, very good quality, perform extremely well. I have been using them for years and have never been dissapointed or had a failure. I would definately rate this item very good and would recommend it to any small block engine builder. Sincerely, Steve gantz

    High Quality at a Low Price

    They look and work just like the original pump and you can change the pressure spring easily. I set them at 50-60 pounds with the medium spring, perfect for stock bearing clearances and street engines. I inspect the insides and the machine work and castings are of very high quality. I will use them again.

    Best gear pump money can buy

    Best gear pump money can buy. I used it as an oil transfer pump and compares to pumps over $100. GPM is great.
