Upgrade Your Milwaukee-Eight with the Feuling OE+ Oil Pump: Better Oil Flow, Cooler Temps, and Peace of Mind
Harley-Davidson’s Milwaukee-Eight (M8) engines are powerful beasts, but many owners know the factory oil pumps can leave something to be desired—especially on 2017-2019 models prone to sumping issues or higher-mileage bikes that could use more consistent pressure and scavenging. That’s where the Feuling OE+ Oil Pump (#7014 for oil-cooled, #7015 for water-cooled/center-cooled M8 engines) steps in as a direct bolt-in upgrade that delivers noticeable improvements without breaking the bank.

Why Upgrade to the Feuling OE+?
The OE+ series is Feuling’s competitively priced “stock replacement” line that’s actually a serious step up from factory. Here’s what sets it apart:
- Billet 6061 Aluminum Construction – Far more rigid than the stock pump for better durability and reduced flex.
- Larger Gerotors – 2" pressure gerotors and 2.25" scavenge gerotors move significantly more oil volume than stock.
- Precision Pressure Relief Valve – Seated and sealed, maintaining a minimum of ~30 psi with full pop-off around 55-65 psi (advertised ~60 psi). This means increased oil pressure right where you need it.
- Better Scavenging – Increased return volumes help prevent wet sumping and keep oil where it belongs.
- Real-World Benefits – Lower engine temperatures, smoother and quieter operation, and more reliable lubrication for better longevity—perfect for daily riders, tourers, and performance builds alike.
It’s a true stock replacement that works with the factory H-D camplate (and other compatible plates). For best results, pair it with Feuling’s #8037 (Drag #0932-0193) OE+ camplate.
