Hey all, I've been searching this lovely little box thats supposed to be full of ALMOST all the information in the world and still can't find anything usefull about these pumps. Ideally I'm looking for an exploded view of thes pumps. I have a small leak on the power side of the pump(drivers) when mounted on and in the engine. It is coming from the piston hole plug. Wich is the opposite side of the Advance cam actuating arm. I dont know if there is a seal of some sort there but it is a cap/bolt of some sort. Maybe tightening it would eliminate the leak, but maybe a bad seal. If anyone knows where you can find a schematic or view of this 8th world wonder would be greatly appreciated. Thanxs guys and gals!!

Advance piston plug leaking???? That's a new one for me, did you try tightening it? 1" wrench will take it off, if its already tight, take it off and get a new o-ring for it, shouldn't affect calibration at all.
