Yes it could be. But, the welded seam around the tank often rots out. The only way to tell is to drop the tank. The bad news is this -- 98 Tahoe fuel tanks are not available from any aftermarket maker ( as far as I know). You must buy one from the dealer. For some reason the 98 tanks are unique to that year only. They cost around $500 bucks. If replacing the tank, I do suggest installing a new fuel pump assembly $250 and a new gasoline filler hose $130 and most importantly a new fuel pump wiring harness connector. If you unplug the fuel pump you MUST replace the harness connector every time -- failing to do so will cause serious problems. Also, make sure you recrimp and clean up the fuel pump ground where it connects to the frame cross member -- just before the fuel tank.
