List of products by brand FEULING OIL PUMP CORP.

Full-travel hydraulic lifters with .200" of travel engineered for high-lift camshafts. Improve valvetrain stability and reduce valve float. Made in the USA.

Full-travel hydraulic lifters with .200" of travel, engineered for high-lift camshafts and increased spring pressures. Maintain critical oil flow and reduce valve float; recommended for strip and performance street engines.

• Performance hydraulic lifters, dyno developed and track tested
• CNC-machined and precision ground for consistent operation
• Increase critical oil flow with a compatible oil pump
• Extend top-end valve gear life; can serve as OEM replacements
• Made in the U.S.A.

• Precision-machined billet construction with square sealing surfaces.
• Longer exit nipples with dual O-rings for improved sealing.
• Optimized inlet sizing and placement for efficient engine breathing.
• Five internal drain ports for controlled drainage and splash resistance.

Precision billet oil pump and matched camplate increase oil pressure and scavenging volumes. Includes camplate relief valve pre-set to 50–60 psi, added oil feed holes and cam journal groove for improved lubrication. Kit includes pump, camplate, retainer plate, and hardware.

• High-flow 2.250" chrome moly gerotor gears for increased oil volume
• Precision-machined relief valve; bench tested to seat at 30 psi, pop-off 55–60 psi
• 42% more scavenge volume and 68% more oil to bearings versus stock
• Magnet protection and corrected passages to reduce wet sumping and blow-by
• Requires matching high-flow cam plate (part #0932-0192) for optimized scavenge

Precision-machined oil system packs for M8 engines that increase oil flow, scavenge volume and pressure while reducing temperatures and wet sumping. Includes pump, lifters, high-flow camplate and installation kit.

Replacement spring and plunger assembly for oil pump pressure relief valve — increases pop‑off psi and restores proper bypass control. Bench‑test with PART #3801-0071.
