Fuel pump video
I know this can't be right and must be the root of my problems. The bowl won't fill up and I got no pressure coming out the FPR.this fuel pump has less than 6 months use.I put six gallons of diesel into the front tank to be sure it had fuel.I have been working on this truck whenever I have a free moment for 7 months. I want and need this truck to run this weekend."God willing and the creek don't rise" I sure hope I posted the link right and y'all can give me some help
PS if the video is to dark tell me and I will shoot another with lighting

That don't look good at all. Remove the hose on the right and connect a long hose to reach a container of diesel and see if it pumps better. If it don't then pump is bad. If it does then you have tank or fuel selector valve issue.

I replaced the airtex fuel pump with a known good carter fuel pump and I didn't get any fuel pumping out this time.I will try the long hose and diesel and see if it will pump. I just noticed my fuel gauge is pegged way past full no matter what tank it is on

I agree.

Since these are mechanical pumps, I need to ask if the shaft possibly fell out, is misaligned, or possibly sticking, and causing the issue.

Switched to the rear tank,it filled the bowl ups lot quicker than the front tank.obviously there is a problem with the selector. The bowl is full and I am occasionally getting wisps of white smoke from the exhaust pipe but still no start

That's where I would start. If someone didn't know what they were doing, it'd be real easy to not notice the tappet missing.
Or your lines have something stuck in them. Blow them out from the engine side with compressed air.
