Base Fuel Pump 25/30 hp

Raised base for fuel pumps.
For 25 and 30 hp engines.
VW Beetle engines 25 + 30 hp.

On Type 1, Type 3, CT/CZ and water-cooled boxer (WBX) engines the flange under the fuel pump can be removed quickly when it has to be taken out of the crankcase. If the flange breaks and a piece is still in the crankcase, turn the engine upside down and tap carefully on the piece that is still stuck. The parts then fall out of the crankcase and the new flange can be fitted. If the engine is installed, try to carefully recover the parts from inside the crankcase. Run the engine for 5 minutes and change the oil straight away (also clean the oil strainer thoroughly) if parts have fallen into the engine. This is still a risky procedure, and carefully removing the pump flange in one piece remains the best option, which is why you are warned.

The main function of the fuel pump base is to prevent heat transfer from the engine to the fuel pump. Gaskets go above and below the base; they are not included, but are available separately in our shop.

Caution: The fuel pump drive shaft (push rod) must be able to move smoothly in the fuel pump base. If necessary the opening in the fuel pump base can be slightly enlarged (does not apply to Type 4 engines). If the shaft cannot move smoothly in the base, it can seize when the engine warms up and the fuel pump is no longer driven.
