does anyone have some good instructions on dropping the fuel tank on a 92' blazer 4.3? i dont know where to start. Thanks

On my '94 it was a pain in the butt.
Get as much gas out of the tank as you can to start off. Mine had a gas tank cover that unbolted to reveal the gas tank itself, held in place with metal straps. Dropping the tank is just a matter of unbolting those and disconnecting everything...which is easier said than done. The filler neck on mine was clamped, and the clamp was turned away, up into the body. So that was a bit difficult to figure out. The electrical connections and i think the vent lines all connect up on the top of the tank.
I'm sure I forgot a few things, I did it a long time ago.
I hope it helps get you started.

Basiclly what SBlazerNCS said. One more thing to add though, if you have a Z engine, you can replace the rubber hose(s) with regular fuel line, as this system runs at a lower pressure. If you have the W engine, you have to replace any lines perferrably with steel line, but if you use fuel hose, make sure its rated at least 100 psi, as this system runs up to 62 psi.
