picking one up tomorrow from a local diesel shop, excited to see how the truck will perform after its in, I know the proper way to install it but still nervous, then I have front frame shackle bushings and rear leaf spring bshings to do 
also, my pump was rebuilt by an athorized stanadyne dealer, however there is no timing scribe on the pump like there is on my current one, the one on my current pump is near the factory mark on the timing gear cover, but this brand new pumps timing mark is right in the middle, underneath the piece where you put a 9/16 wrench to rotate it, *** is up with this? I'm not sure what to do now
