Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Harley Bike Oil/Water Pumps and Parts

  • Compatibility: Ensure pumps and parts fit your Harley's engine type (e.g., Twin Cam 88, Milwaukee-Eight M8 oil-cooled/twin-cooled). Use the vehicle selector for model-specific matches (e.g., Twin Cam or M8) to avoid flow or pressure issues.
  • Type of Use: For high-performance or racing, opt for Race Series pumps with billet construction; standard rebuilds or upgrades benefit from HP+ or OE+ series for increased pressure and scavenging in street conditions.
  • Components and Upgrades: Select oil pumps, camplates, oil system kits, pressure relief valves, covers, or mounting kits. Focus on features like high-flow gerotors, bench testing, and billet aluminum for cooler temperatures and better oil flow.
  • Brand and Quality: Choose Feuling Oil Pump Corp. for premium billet pumps and systems with military-spec anodizing, or Colony for OEM-style mounting kits. Prioritize USA-made materials like 6061/7075 aluminum for durability and heat resistance.
  • Installation and Cost: Most parts are bolt-in with bench-tested reliability; kits include all components for overhauls. Prices range from $12.95 for valves to $1,229.95 for race systems—factor in free shipping over $99 and expert support for value.

Frequently Asked Questions (FAQs)

  1. What Harley models and engines do these oil/water pumps and parts support? Parts support Twin Cam 88 and Milwaukee-Eight M8 engines (oil-cooled/twin-cooled)—use the year/make/model filter for exact compatibility.
  2. How do high-flow oil pumps improve performance? They increase pressure (15-30 PSI), scavenging (60% more), and reduce temperatures (25-35° cooler), eliminating wet sumping and oily air cleaners.
  3. What is typically included in an oil system kit? Kits include oil pumps, camplates, and components for full overhauls, with options for HP+ or Race Series.
  4. Are these parts bench tested? Yes, Feuling pumps are bench tested for relief valve seating (30 PSI min) and pop-off (55-60 PSI), ensuring reliability.
  5. What if a part doesn't fit my Harley? Verify engine type (Twin Cam/M8) and specifics before buying. Our returns policy allows exchanges or refunds if it doesn't match.
  6. Can I find related engine parts? Yes—explore gaskets, pistons, or cams in the Harley engine category to complement your oil pump upgrade.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.
