AP Fuel pump

[Geoff Dowdle]

Peter,
The Pump is a AC brand ( I don't believe there is any connection with AC Cars Ltd) , there are many variations of the same pump fitted to many British cars of the 40's , 50's & 60's
Bases vary in their bolt pattern to the block
The lever that operates the pump from the cam was made especially for Bristol .
Tops (above the diaphragm ) vary a lot also .
The operating rods on the diaphragms vary also

The closest I've found over the years are tops and bases from two different model Standard Vanguards of the 50's but you still need to use the original operating lever from the Bristol AC Pump .
