Frequently Asked Questions
How do I confirm this Boundary part matches my engine?
Match the exact Boundary part number, engine family and generation, original pump housing, crank drive, pickup, oil pan, pressure and volume requirements, and every manufacturer application note. Do not select it from vehicle model or engine nickname alone.
Can I install this part without measuring engine clearances?
No. Oil-pump work belongs in a controlled engine-build procedure. Inspect the housing and rotating parts, measure required clearances, verify pickup and pan compatibility, establish pressure targets, and follow the engine builder's assembly plan.
Does this include every part needed for the oiling upgrade?
Only parts expressly listed for this exact manufacturer part number are included. Housings, back plates, gears, seals, fasteners, pickups, pans, gaskets, fluids, primers, and related engine components may be separate.
Installation Instructions
Follow the current Boundary instructions, engine builder specifications, and factory service information for this exact part number. Disassemble in a clean environment, inspect the housing and rotating components, measure all required clearances, verify pickup and pan compatibility, lubricate and prime the oiling system, use specified sealants and torque values, rotate the assembly by hand, confirm oil pressure before startup, and inspect for leaks. Professional engine assembly is strongly recommended.
