Ok so I am looking for some advice on the best way to make sure the pinned timing on my p 7100 is accurate. I have the engine at top dead center and the pump is pinned. I will be puttin a set of 75 horse 24 v injectors in it that are popped for a 12v any information on the set up of the adjustable pump gear and the correct spot my pump is supposed to be pinned at would be greatly appreciated. Thanks.

 

Or maybe just how to accurately make sure the pump is pinned where it is supposed to be pinned at I got the pump from a guy . He said it came off a bread truck and I want to make sure it has not been messed with. If there is anybody that can tell me how to set the pump at tdc without the pin I guess that is the real question.
