AP Fuel pump

[Geoff Dowdle]

Peterg,
what is the history of the pump ?
Have you ever had it running correctly on a Bristol engine before ?
or did you just purchase it and this is your first trial run?

I had a similar problem a few years ago , rebuilt a pump for a new engine in the 400 . After a few miles had fuel starvation problems .
I found for some reason the operating lever that runs on the camshaft was bent , this meant the lever was not giving the pump the full stroke and inturn not the correct pressure .
I checked the lever against another original one , straightened it , and it has run at correct pressure since.
These pumps are usually trouble free after fitting a rebuild kit .
Bristol 450's used them for Le Mans without a problem
