Abstract
An oil fill tube for an internal combustion engine, the engine including an oil sump contained therein. The oil fill tube is axially flexible, and includes an extendable and contractable accordion section intennediate first and second ends, the first end sealingly affixed to a fill hole in the engine housing such that oil may be filled through the oil fill tube into the oil sump. The flexible, extendable, and contractable accordion section of the oil fill tube allows a single oil fill tube to be used with a variety of differently sized engines, and also dampens relative vibration between the crankcase and shroud of the engine housing to reduce tension on the fitting between oil fill tube and crankcase and to prevent oil leakage therethrough from the oil sump. A variety of fittings between oil fill tube and crankcase provide a secure, leak-resistant connection therebetween.
