Melling Performance 10341 - Ford 4.6L & 5.4L Performance High Volume Oil Pump.

Description

Made in the USA to the highest production standards, Melling high-performance oil pumps deliver dependable lubrication and maximum durability under the toughest RPM conditions. Engineered as a high-volume performance upgrade for the M340HV, this pump is specifically designed for Ford Modular 4.6L SOHC and 5.4L DOHC engines demanding increased oil flow. Utilizing the latest in gerotor technology, it displaces 20% more oil volume than the standard M340, M360, and 10340 pumps to support high-demand performance applications, auxiliary cooling lines, and loose bearing clearances. The pump features an anodized hard-coated cast aluminum body paired with a phosphate-coated cover for superior wear resistance, precision-ground end plates, and gears machined to exacting tolerances. Pre-assembled with an 80 psi high-pressure spring and supplied with an interchangeable 60 psi spring, it allows builders to tailor relief pressure via a serviceable threaded valve plug. Every Melling oil pump is individually tested for pressure and flow under simulated engine operating conditions to ensure flawless operation right out of the box.
