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)
- 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.
- 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.
- 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.
- 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.
- 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.
- Can I find related engine parts? Yes—explore gaskets, pistons, or cams in the Harley engine category to complement your oil pump upgrade.
