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.
The pump is 1-1/4" longer than a stock oil pump, so oil pan modifications may be necessary to provide clearance.
