(133133511) - Fuel Filter - Air Cooled VW (75-85), Porsche 914 (70-76) (1 available)

133133511 (often written as 133-133-511) is the official factory part number for a classic Volkswagen / Audi / Porsche inline fuel filter. This one is famous for its distinctive square plastic or gray rectangular housing rather than a standard cylinder body. It is designed with an 8mm inlet port and a larger 12.7mm (1/2 inch) outlet port to feed directly into early electronic fuel injection (EFI) fuel pumps. (gar2-Y2)

This fuel filter is the stock factory placement for classic German air-cooled and water-cooled fuel-injected vehicles from the mid-1970s through the 1980s:

• Volkswagen Beetle & Super Beetle: 1975–1979 models equipped with fuel injection.
• Volkswagen Type 2 Bus / Transporter: 1975–1979 fuel-injected models.
• Volkswagen Vanagon: 1980–1985 early-generation models (specifically placed upstream right before the fuel pump).
• Porsche 914: 1974–1976 targa models featuring the 1.8L or 2.0L H4 fuel-injected engines.
