FEULING OIL PUMP CORP. Vented Dipstick - Polished - FL 3091

Big-displacement M-Eight engines produce excessive blow-by that accumulates pressure in your oil tank—causing seal failures, oil leaks, and accelerated wear. The FEULING Vented Dipstick actively vents this pressure while letting you monitor oil levels accurately, eliminating guesswork on baggers where oil slosh varies with riding position. This bolt-on replacement transforms a common big-bore problem into a non-issue while keeping your engine breathing clean.

Choose Your Venting Setup: The 1/8 NPT breather option delivers a clean aesthetic with internal filtration, ideal for moderate blow-by. The quick-disconnect coupler with hose routing option handles excessive oil misting by capturing residue in a remote filter element—routes cleanly along frame rails and under the seat for a factory-finished install.

Oil Level Reading: Two measurement points accommodate different riding positions. Use the FHS (Full Hot Stand) dimples when checking on the jiffy stand, or the FHU (Full Hot Upright) dimples when the bike is level and upright. Allow the engine to warm up off the kickstand to ensure accurate readings—idle time on the stand will skew tank levels due to oil migration in the case.
