GMC Repair: Fuel Tank removal/drop, tank removal, fuel sending unit

Question
Hi Marc:

I want to drop my fuel tank on my 2004 Sierra Denali pickup.  Could you advise where I can find detailed instructions on doing this?

Thank you for your time,
Keith Fujimoto

Answer
well I can give you a personal run down make sure when you do this have less than a qtr tank first then drop out there should only be four bolts on this You also need to unscrew the filler to the fuel door and it should slide down but get something to hold the fuel tank up/ Are trying to replace fuel sending unit or something like that
