Replaced dead fuel pump on '98 K2500 at 196K miles. Since I knew the job would be difficult for me (I'm 82) and so wanting to do it only once, I bit the bullet and bought the pump from Chevy according to VIN, but for a gut-wrenching price (GM 19369943 module kit). Installed and tested system with tank still on ground and truck starts and runs as normal. However, when I turn on the key the fuel gauge slams hard enough upscale to make me wince, and then immediately back down to near empty which would be about right for the amount of fuel in the tank (now ~3 inches in 32 gal tank). Don't know yet if it will track as I add fuel. Any idea why this is happening? It wouldn't be a grounding issue, I wouldn't think, as the pump itself runs normally. Whatever it is I ain't doin' the job again, but I would sure like to know what's going on. I liked things much better when fuel pumps were mounted on the block - where they belong!
FYI, I decided to drop the tank, which was full, rather than raise the bed and I'm glad I did. Even with the tank out and in the backyard it was nearly impossible to push the pump unit down against the O-ring uniformly enough to get the retainer in place (a snap ring rather than a tabbed ring). Differences between old and new is that the pump/fuel gauge connector is of a different design such that the old connector has to be cut off and replaced (new one supplied with pump assy. kit), and the bottom external fuel strainer/sock has been eliminated, thus making them more money per unit while affording you less protection.
Finally, I did have some luck. The old pump died quietly at home and not out on the road. I am hoping for the same.
