Fuel Pump

December 2003:

The mechanical fuel pump is mounted on the side of the block - note clag in the valve chest!

The replacement diaphragm is apparently more suitable for unleaded fuels - the old one was OK but showing its age!

The two simple valves were clear of any contamination and were just cleaned up

The reassembled pump ready for putting back into the block, though the dome filter gasket subsequently needed some gasket sealant to ensure an air-tight fit.

Very conveniently, the petrol pick-up pipe ended just inside the drain plug.  It was easy to push a flexible pipe over the end and confirm that the pipework was OK by blowing from the fuel pump end into a small jar of petrol - it was!

A gallon or so of petrol into the tank - no leaks (but see fuel tank page) - and the pump enthusiastically squirted petrol in the direction of the carburettor.
