Upper Oil Filler Pipe (Includes Cap And Clip) - Type 4 Engines

This replacement upper oil filler pipe is designed for Volkswagen Type 4 air-cooled engines in 1700cc, 1800cc, and 2000cc configurations, as fitted to Baywindow Buses from 1973 to 1979. It replaces the original upper filler tube that allows clean and controlled engine oil filling via the engine bay.

The upper oil filler pipe connects to the lower filler assembly and provides a secure mounting for the oil filler cap. A cracked, corroded, or loose filler pipe can allow dirt and debris into the engine or cause oil leaks and fumes in the engine bay. Replacing a worn filler pipe is essential for maintaining proper crankcase sealing and clean oil servicing.

Supplied as a complete assembly, this unit includes the oil filler cap and retaining clip, allowing straightforward installation with no additional parts required. Manufactured as a good quality reproduction, it is built to original dimensions for correct fitment and long-term reliability.

Ideal for engine restorations, routine maintenance, or replacing damaged original components, this filler pipe restores correct oil filling function and engine bay appearance.
