    Note that the correct fuel pump rocker arm for the Bristol 2 litre engine (the part that is operated by the camshaft) is different from that on any other UG model AC fuel pump. Its number is 1524280 – this number is cast into the arm itself. This information was put on the Enthusiasts Forum by Geoff Dowdle, and I can confirm that this information checks out with my 403’s fuel pump.
