So this would work?

ok so it looks like i will need a 3/4 wrench to hold the fuel line in place while i turn the nut with a 1.25 wrench on the fuel pump, but really it is an injection pump.
definately replace all the little rubber connection lines while im in there. its definately a mechanical pump that looks similar to the one in that pic but i notice the one in the pic i didnt see the 1.25 nut on the backside of it. of course it only shows the frontside. yep definately one of the differences between the t444e and the powerstroke 7.3 is the location and kind of pump.
i will look into the possibility of updating that regulator if need be. thanks for the heads up, would be nice if i could get a quieter purr out of her at idle too.
i was looking at scanners now that u mention it. because navistar uses diamond does that mean that i wouldnt be able to use a simple obd2 scanner like the cheap ones found on ebay?

so i took out the two lines from the top of the fuel pump, and i took out a line from the front of the pump on the bottom and another from the back of of the pump on the bottom. i took off the bolts on the right and left side holding the pump down. now i am trying to pull the pump straight up and it doesnt want to come up. do i need to gorilla it up or am i doing something wrong?

Just pull straight up. Sometimes they are pretty stuck.

i watched a vid warning about losing your anvil (the bottom plunger part of the pump that goes into the engine), and i followed their suggestion, which was to turn the main crankshaft a little in order to raise something in the engine that blocks the hole so the anvil cant drop down into your oilpan.
i think that loosened it up enough that it would start to twist a little bit. i had to gorilla it out while twisting. i guess i didnt realize the circle where the bottom of the pump mates with the engine was so thick.
it finally popped out. i was very careful not to bump the anvil on the engine wall as i raised it out just out of paranoia. upon examination after a cleanup, the weep hole was still steadily weeping. so i guess that answers that; worn pump.
i just hope it goes back together quicker than it came apart
someone suggested i put grease on the anvil. do u guys do that?
