Fuel issues
So last night was the first time I've ever been stranded by a Ford, I know it's crazy. So driving down the road and my truck begins to shudder like it's out of fuel I'm thinking why I just filled up tank reads full. So pull over I've got spark , and fuel pressure so I try to key it runs then immediately dies. Check my fuel filter since I'm new to the truck I bought one on the incase, nothing new starts then dies. So I check pressure again and I have no pressure, dropped the rear tank walked to O'Reillys bought a fuel pump for the rear tank and installed it on the side of the road. Motherf***** starts right up runs all the way home. So my question is do the tanks transfer fuel between both or is it dual fuel pumps. Also should I be waiting for something else to break in reaction to this?

You do have three fuel pumps on that year truck.
You didn't mention it, but if only the rear tank pump had failed, you should have been able to start when the front tank was selected.
In other words, if you tried the front tank and it did not start, you may very well have another problem.

My 89 has three pumps, one in each tank and one on the rail. Mine died running from the rear tank even though I had just filled up. Switching to the front tank and all was good and for now I'm just not using the rear tank.

Well, I'm glad RLA put that up, as I really thought it was a three year run for that set-up.
I run two 89's.
But there's that issue of not starting on the front tank.

Possible bad high pressure pump in the front tank, wiring or bad fuel selector switch. Process of elimination via troubleshooting with a test light.

A handy diagram to help you out:
It's for a 1991 but should be very similar to yours.
Jumper pins 2 & 6 on the diagnostic connector under the hood then turn the key to the On position. This will keep the selected fuel tank pump energized. Use a test light to trace out the power to the pump.
