Blowing fuses while switching fuel tanks

My 1994 Ford is blowing fuses when I attempt to switch from the rear fuel tank to the front tank. The wiring looks protected inside of a loom. I have not taken the loom apart yet.
Has any one ran into this problem before and what was the cause?
Also, Do the 1994 diesel Powerstroke trucks have one fuel pump for both tanks, or does each tank have its own pump? And where is it located?

Thanks,
Scott

The pump is mechanical, run by an extra lobe on the camshaft. It's up in the engine valley.

Does the truck actually run on the front tank? Does the gauge work on the front tank?

I can't switch to the front tank. The gauge hasn't worked on the front tank since I purchased the truck. I used to use it as a reserve.

If the pump is mechanical then the problem might be in the fuel switch under the cab.
Thanks,
Scott

As already said This problem is normally cause by a blown solenoid. Start with the one on the tank, disconnect it and see if the fuse blows when switching to gas, if necessary repeat for the other solenoids.

Solenoid on the tank? Switching to gas? What on earth does that mean?

Pallet trucks, pump trucks, pallet stacker, pump trucks, hand pallet truck
Just how many solenoids are there? I was only aware of the one switch under the cab. I like the Idea of disconnecting it and seeing if the fuse blows when switched.

I'm sure it was just a type O, but this is a Diesel system with 2 fuel tanks that we are talking about.

Thanks,
Scott

There are no solenoids on the tank. The selector under the cab switches the supply, the return and the gauge feed.
