Boundary Assembled Modular V8 Oil Pump 4.6L & 5.4L (MM-S1) - Ford Modular V8 Applications
Give your modular 4.6L or 5.4L the oiling upgrade it deserves. The Boundary MM-S1 Assembled Oil Pump is built around the high-flow 3V housing and comes ready to install with Boundary’s mirror-finished billet gears. It’s the ideal solution for street, boosted, or track modular builds that need stronger gears and better protection where the stock pumps fall short.
Boundary starts with the 3V housing because it uses the largest modular pump gears available, providing more oil flow than DOHC or early SOHC pumps. That higher volume helps protect bearings through the mid-range and low end, while the larger gear set adds strength for high-RPM or high-load scenarios. Every pump is fully torn down, ultrasonically cleaned, de-burred, and hand-inspected before being reassembled with stainless Torx hardware, Loctite retention, anaerobic sealant to reduce aeration, and assembly lube for rapid startup oiling. Each unit is blueprinted and ships with a spec sheet, and it’s plug-and-play for all 15/16" pickup tube vehicles—bolt-on and go.
