Also when pushing towards the motor (I believe this is the correct direction)it seems there isn,t enough adjestment to get to 24 BTDC.This is w/o the lines atached etc. Is it possible the pump was not properly installed to give enough adjustment? It looks like the timing chain is recent( only 1.5 deg stretch) What do you think?

If the timing chain is recent, there should not be a problem to get to 24 BTDC and you might have something amiss in your procedure.
To be 9 degrees retarded with a brand new chain is almost impossible unless someone removed and reinstalled the pump improperly in the past.
Take a look for the IP alignment marks. There is a mark on the IP flange and a mark on the block. These marks were supposedly in alignement when the vehicle was shipped from the factory.
The SD has 2.5 degrees of stretch in the chain and it makes it to 24 BTDC, but without much capability of going any further.
One additional point to note: If the IP won't go closer to the engine, but, you can't see where it's hitting the engine up near the top of the IP, then, in all likelihood, you have failed to properly loosen the lower screw that secures the IP. This screw is very difficult to find and even more difficult to move. It must be done from the top with a long box wrench that reaches down between the back of the IP and the oil filter housing.
Many folks have failed to set the IP properly because of the inability to find and properly loosen this lower screw.
