Tell me about how you resolved the lock fuel pump. My wifes Suburban won't start if she has less than 1/4 tank of gas and she attributes it to this problem.

The pickup version of the same chassis is easy, 8 18mm bolts and a few wires pops the bed off and you can put it in with the tank still attached. Some people will cut a hole in the floor, I’m not quite that much of a butcher, but a factory access panel would be awesome.
Low lock refers to the 4WD system. Totally separate issue from the fuel management.
