Melling High-Volume Oil Pumps

Melling high-volume oil pumps give you an additional 20 to 25 percent of much-needed oil volume for your performance application. For those of you who need added pressure, many pumps are supplied with a high-pressure spring (where noted). The pumps are built using a proprietary casting process, which yields maximum performance and reliability. Every Melling oil pump is completely pressure-tested, including idle and bypass pressure, before it leaves the factory. Dozens of models are available for fitment; order the pump and options needed for your vehicle.

Q:

Will this pump work with a 5.7 vortech engine? (1998 Sierra)

Asked by DAP on 9/30/2017

DAP, The correct high volume pump for your application is the M155HV, it will have a 3/4 inch pickup tube instead of the 5/8 inch tube used on the M-55HV. Thanks

Q:

I received my Melling M55HV with a purple bypass spring. I can not find this pump/spring combination on the Melling website. Is this a valid pump/spring combination and if so what is the bypass oil pressure?

Asked by DAVID on 11/22/2017

David, the factory installed pink/purple spring has a 70 PSI bypass. Thanks.

I have used this pump many times my engines run about 60 to 70lbs cold about 40 to 45lbs warm at 1000 rpm and about 50 to 60lbs at 2500 rpm I also block the bypass for the filter so all of the oil has to go through the filter hope this helps

HIGH VOLUME PUMP

10/18/2014

Summit Racing Equipment Summit Racing Verified Purchase

MEL-M55HV
Melling, trusted made in USA oil pump. Still sitting on the stand but in previous applications I’ve always had 75 psi cold start and around 60 psi hot. Highly suggested you buy a hardened intermediate shaft for this pump. And paired with a new Melling oil pickup, should be a great combo.
