Feuling

Feuling is an engineering company known for its work on Twin Cam lubrication, and this page lists the Feuling parts in the catalog. Almost everything here is for engines that are being rebuilt or upgraded, mostly Twin Cam but with some Evolution fitments.

Oiling and engine parts

HP+ billet oil pumps are listed for Twin Cam 2006 to 2017, and HP+ oiling system kits fit Twin Cam. Fast Install tapered push rods are made for Twin Cam and Evolution. A 12-point exhaust stud kit for Twin Cam gives a firm exhaust fit. A few shop tools complete the range.

Why Twin Cam oiling matters

Riders building a performance Twin Cam often upgrade the oil pump and related parts, because a stronger build asks more of the oiling system. A well-matched pump helps keep pressure steady across a wider rev range, which matters when you add cams, displacement or sustained high rpm use. Always check your engine's year, cam type and displacement before ordering. Parts for the Twin Cam engines built before and after 2007 are not always interchangeable, so read the year range in the title.

Planning the build

Use clean parts and fresh oil, and follow the instructions during installation. An oil pump swap involves opening the cam chest, so plan for new gaskets and seals. Feuling parts are sold for off-road and closed-course use only. See engine upgrades for cams and big-bore parts, gaskets and seals for the rebuild set, and KPMI for valve parts.
