I found one morning the Suburban wouldent start, the starter run fine but no gas, I'd just fueld the rig last week so had plenty of gas, I couldent hear the gas pump when turning the key, I checked the pump relay in a diffrent suburban.....it started just fine, Damn so the fuel pump was bad, This 1999 Suburban still had the original gas pump, I was lucky I had a buddy let me use a corner of a heated hanger to work on it, it was subzero outside and living on the Arctic coast of Alaska its no fun working outdoors on stuff with plastic parts, I siphoned as much gas as I could
and jacked the back end and put a pair of stands under the rig, disconnected the battery ground(-), the gas tank removal had some snags as all our fine silt turned to slop and oouzed off snow and ice dripping, every fastener was siezed with rust, so after snapping off all the guard bolts(they wouldent budge either tighten or loosen) I had access to the tank strap bolts, just looking at the blisters of rust I knew they were not going to come loose so I sawd em off useing a air powerd hacksaw(panel saw) the only other trouble I encounterd was useing a NAPA brand fuel line dissconnect tool wouldent fit in the connecters, (I drilled the tool scissors rivet) and then was able to tip each end the tool into the fueline fittings to get them released.
On reassembly I was able to drill and tap all the tank guard holes(hardware stor metric boltz for replacements), I used galvanized all thread (reddi rod) as the new hanger strap bolts, and lots of Anti Seize on reassembly
There was no way I would have been able to get the pump seal O-ring to seat if I did this out in the cold!
Due to the brakish mud we have here on the coast I was certain to seal the electrical crimp splices that came with the pump (plug adapter kit in box) I seald the wires useing liquid electric tape and wrapped the bundle well with Vynil electricians tape.
