Your going to have to find the short. Fuse 22 powers the pcm as well. By the hpop reservoir there is a wiring clip that goes to the icp,ipr, fuel bowl heater, and water in fuel light IIRC. Unplug it and see if the fuse blows. You truck won't run with it like that but it will tell you if the wires running below the fuel bowl have rubbed through.

Sorry I wasn't clear enough. The harness you will be looking for goes from the bowl heater under the bowl and up the other side where it connects into the main harness. There should be a multiport connector either Close to the main harness or inside it. Sorry I don't have a pic and I modified my harness for efuel. Ie no more of that stuff
