you can have my mech fuel pump if you buy me a block off plate ($6 on summit). I bought it last dec. I have an electric one now for fool injection.
Your pump is located on the drivers side of the block. Just follow the metal fuel line down to the side of the block.
Oh, and mine had 2 fuel filters, one was inside the frame rail right under the door. Check that one. On the way back from k2 last year my truck kept shutting off and we couldn't figure out why. We took off the filter, which was pretty new I might add and it was clogged. We waited till we bought a new coil to figure that out though.......
