FEULING OIL PUMP CORP. Vented Dipstick - Polished - Dyna 3089

Excessive blow-by in big-displacement engines causes oil sump buildup and pressure that degrades engine seals and breather systems. The FEULING Vented Dipstick solves this problem by actively venting unwanted pressure through a dedicated breather circuit while providing accurate oil-level monitoring. This is essential maintenance for M-Eight baggers running large-bore kits or experiencing ring leakdown.

Two venting configurations let you choose between aesthetics and convenience. The 1/8 NPT option delivers a clean look with an internal porous filter, while the quick-disconnect hose setup routes excessive oil misting away from the engine bay—simply route the line up the frame rail and secure the filter element between the engine and transmission. Dual oil-level reference marks (FHS for jiffy stand, FHU for upright position) ensure accurate readings in any orientation.
