I think you're correct. The fuel pump is located in middle center of inserted into the tank from the above.
I just looked this up in the GM's official service manual (phonebook-thick, heavy, 3-volumes). The detailed instructions of how to do this procedure spans for several pages.
It seems the procedure involves:
- disconnecting the gas tank from the inlet hose which originates from the chrome fuel door.
- disconnecting the evaporation vent pipes (metal, small-diameter, long, and winding)
- dropping the entire fuel tank.
- draining the gasoline and handling care.
- removing and replacing the ruined fuel pump.
Wow, I didn't know there is so much involved.
(disclamer: I don't have a personal experience doing this, just a wannabe mechanic with manual)
I had the same experience that OP is having. One time, there was a knee-deep flood on freeway caused by busted water main. I proceeded to ford and go across this big 50-yard puddle while every other driver in regular car is inundated and stuck. They looked at me with envy. My H2 drove fine at 60 mph to my home with no hint of any malfunction. But next morning, its engine cranked but could not start and CEL came on.
I had to get my H2 towed to the dealership, and they fixed it under warranty.
The owner's manual specifies that H2 can ford water up to 20 inches, but this needs to be done at below 5 mph. Too bad, I was going faster than creating walls of splash curtains and enjoying it.
