87 Trooper Fuel System
 

I was just asked to help a budy on his 87 Trooper with fuel problems. I have not seen the truck yet so im only going off of what he telsls me and a few quick web searches. Frome what I can tell an 87 calls for a mechanical pump but he pulled an electric pump out of the tank. If someone could give me a quick rundown of the basic fuel system for these trucks that would be awesome.
