Ok..... Got the pump installed and have a few questions. I know the timing on the pump in firing stroke TDC on front cylinder. Is says to pin the crank in the manual but shows no description of how to do this. We took the injector out and used a screw driver to tell when the piston was as the top and made sure that both intake valves were closed. We had the valve cover off too. We had the timing marks lined up on the injection pump too. My two questions are..... Does anyone have a pic of where the hole is to access the flywheel to pin the crank and also with having all the fuel lines loose as well as a dry injector pump. What is the best method to getting everything bled back out. thanks for all the help with everything. Just stumbled across the site while researching what could be wrong
