It6's really not too hard at all but you do have to remove the gas tank.

I did it the lazy man way and did not drop the tank.
I made a access panel in my bed, then i had to bondo the top.
After putting the herculiner on it doesnt stand out at all.
But if i had a chance to do it again i would have dropped the tank and do a shackle flip at the same time
added two pics of bondo fix before herculiner

I also cut a 12"X6" access panel in the back of the blazer to get the sending unit out. It was a lot easier the dropping a 3/4 full tank, reciever hitch and flatbacking it by myself. I used a sawsall blade that i cut down to be 2" long as not to cut into anything vital, then tacked some tabs a remounted the cut out plate w/ some screws.

Your pretty brave with a sawzal, I used a dremul 
You might be able to repair the sender depending on what the problem is, fixes have been posted to the board before. The senders are quite pricey.

Thanks guys, when I got my Blazer the sending unit was bad, now I think my fuel pump is starting to go out (149000 miles) so its time to replace both. I got the sending unit from LMC Truck, it was 99.00 dollars, I got a new fuel pump for free so this isn`t costing me as much if I would have had to by both parts.
