FEULING OIL PUMP CORP. Short Sump Plug - M8/Twin Cam 3115

If you're running a Harley-Davidson M8 or Twin Cam engine and want to maximize oil scavenging efficiency, this short sump plug is essential. By eliminating obstruction at the internal engine case scavenge pick-up hole, you allow your oil pump to pull maximum volume from the sump—directly improving lubrication under high-demand racing conditions. Factory-height plugs can restrict cross-sump port flow; this purpose-built alternative ensures unrestricted oil delivery when it matters most.

Feuling Oil Pump Corp. engineered this plug to account for the critical differences between M8 and Twin Cam engine cases, where factory machining creates the sump cross port at varying heights. The result is a bolt-on upgrade that restores full pump capacity without modification.
