This replacement fuel pump flange is fitted between the mechanical (manual) fuel pump and the crankcase on Volkswagen Type 4 aircooled engines with capacities of 1700cc, 1800cc, and 2000cc. It is used on carburetted engines fitted to Baywindow Buses and early Type 25 (T3) Buses up to 1983.

The flange serves two important functions. First, it correctly spaces and supports the mechanical fuel pump, ensuring the pump pushrod operates at the correct height and stroke. Second, it provides a stable mounting surface and sealing point between the pump and the engine case.

This flange is not used on fuel-injected engines, as those systems do not use a mechanical fuel pump driven by the engine.

Over time, original fuel pump flanges can become damaged, warped, or lost during previous engine work. An incorrect or missing flange can cause fuel delivery issues, oil leaks, or premature wear of the fuel pump and pushrod. Replacing the flange restores the correct factory geometry and helps ensure reliable fuel pump operation.

This is a good quality reproduction flange, manufactured to the correct dimensions for direct fitment on Type 4 engines.

Fitting notes:

• 1 flange required per engine

• Requires 2 gaskets (one above and one below the flange)

• Recommended gasket part number: 021127311A

Other parts that may be required or worth checking when fitting:

• Mechanical fuel pump

• Fuel pump pushrod

• Fuel hoses and clips

• Pump mounting nuts and washers

Correct installation of the fuel pump flange is essential for proper fuel delivery and long-term reliability of the mechanical fuel pump system.

Quantity

• Sold individually

Applications

• VW Baywindow Van (Type 4 carburetted engines): 1973 – 1979

• VW Type 25 / T3 (aircooled, carburetted): 1979 – 1983

This replacement mechanical fuel pump pushrod is designed for Volkswagen Type 4 aircooled engines with capacities of 1700cc, 1800cc, and 2000cc. It is fitted to Baywindow Buses and early Type 25 (T3) Buses that use a mechanical fuel pump on carburetted engines.

The pushrod transfers motion from the engine to the mechanical fuel pump, driving the pump diaphragm and allowing fuel to be drawn from the tank and delivered to the carburettor at the correct pressure. The correct pushrod length is essential, as it directly affects fuel pump stroke and fuel pressure.

A worn, bent, or incorrect-length pushrod can cause poor fuel delivery, fuel starvation, or excessive fuel pressure. This replacement pushrod is manufactured to the correct 139.8mm length, ensuring proper operation when used with the correct fuel pump flange and gaskets.

This is a good quality reproduction pushrod and is ideal for replacing worn or missing originals during engine rebuilds, fuel system repairs, or routine maintenance.

Important fitting notes:

• For use with mechanical fuel pumps only

• Not suitable for fuel-injected engines

• Ensure correct fuel pump flange and gaskets are fitted

Other parts that may be required or worth checking when fitting:

• Mechanical fuel pump

• Fuel pump flange

• Fuel pump gaskets

• Fuel hoses and clips

Correct installation of the fuel pump pushrod is essential for reliable fuel delivery and long-term engine performance on Type 4 aircooled engines.

Measurements

• Length: 139.8mm

Applications

• VW Baywindow Van (Type 4 aircooled): 1973 – 1979

• VW Type 25 / T3 (aircooled 2000cc): 1979 – 1983
