First, you"ll need accessibility to the floorboard. You must remove the behind driver"s side seat. It"s simply two nuts. Relocate the chair forward, take turn off the 2 bolts, and also pull out the seat. Climate you remove the trim native the bottom that the behind driver"s next door jamb and also the B column trim. Move the former driver"s seat up every the method to give yourself a little more room. Move the carpet by make a pair inconspicuous cuts. Be mindful of the wire impend that runs ideal over the fuel pump.I drilled a 3/4" hole wherein I knew the pump was so I might figure out specifically where I necessary to cut. The fuel pump is right between the 2 studs that host the the seat down. Once you figure out wherein it is, usage the nibbler to cut as large a hole together you deserve to over the fuel pump. I supplied a socket to host the wire impend up out of the way. There is a weld front-ward that will be your north boundary. The increased area where the chair mounts will be the western, eastern, and also southern boundaries. Rotate the head the the nibbler if you need to. As soon as you have actually a rectangle-ish shape cut out, you"ll likely see this:

Pull relay 41 under the hood and crank the engine to depressurize your fuel system. Curse, swear, and eventually eliminate the fuel lines indigenous the fuel pump "simply" pinching the clip and also pulling the hose off. Rust it s okay stuck in between the clip and also the line, so I ended up wiggling them until the lines damaged off; the made removed the lines indigenous the fittings a bit easier. My AC Delco fuel pump didn"t come v the plastic clips, so conserve your old ones. Usage that pneumatic hammer us talked around earlier, and knock the retaining ring off. Ns think this job would have actually been difficult without it due to the fact that of the room constraints. The specialized tool to take off the ring may have worked, but I reduced a hole in the floorboard of my TB. Girlfriend think ns buy committed tools??? NOTE: Before and after remove the ring, ns vacuumed off every one of the rust and crescent-shaped piece of metal. Using the hammer will knock a many rust off. Girlfriend don"t desire that in her tank.

Install your new pump and lock ring. Ns wouldn"t reuse that old, rusty ring. Again, the pneumatic hammer to be a necessity. Reconnect the fuel lines and also electrical connector. Begin your van to check out if petrol is spewing out like before. It"s not. Success!

Paint the edge of the floorboard that you reduced so the doesn"t rust, then usage a nibbler to cut some sheet metal of similar thickness to a small bigger than the hole. Repaint it, don"t wait for it to dry fully (because that doesn"t like repaint covered fingers?), placed a bead the RTV approximately the hole, and pop a couple of rivets in. Self-tappers would job-related as well, but just make sure they"re short.
