Product Description

The Boundary MM-S1 is a Stage 1 assembled oil pump built on the larger-volume 3V housing for the Ford Modular V8, engineered for the 4.6L and 5.4L platforms across the Mustang GT, Mustang SVT Cobra, F-150, F-250/F-350 Super Duty, and Expedition (excluding 6.2L applications). The 3V housing includes the largest available pump gears of any Modular pump option, providing a genuine boost in mid-range and low-end engine protection along with added strength from the larger gear set.

Every pump is completely disassembled, ultrasonically cleaned, air blasted, and hand inspected before being hand de-burred and rebuilt with Boundary's industry-leading mirror-finished billet gear set. Stainless Torx head fasteners replace the stock hardware, torqued to spec with Loctite applied to prevent back-out, and anaerobic sealant is applied to critical areas to boost pump-up speed and reduce aeration. A precision-machined O-ring groove on the pump mounting face delivers a positive seal between the pump and engine block, reducing leak risk and improving sealing under higher oil pressure.

This pump is intended for Modular V8 owners running the 15/16ths pickup tube who want a genuine, machined-in-the-USA upgrade over the factory pump. It bolts on and requires no additional lubrication or modification; parts are blueprinted and shipped with a specification sheet, and the pump is backed by Boundary's lifetime warranty.
