Just did this repair. Special thanks to NickXXX for starting this thread and Bearcatdon for all that good info!!! 1st I'd heard for the warning about the tightening sequence.
Note: My torque wrench took a dump so I did the job without it. I paid alot of attention getting all the bolts torqued the same. Much to my suprise I've had no problems whatsoever. I guess I've had enough troubles in the past. Somebody likes me.
If I had to do it over I would be smart and get a torque wrench though.
p.s. don't lose the fuel inlet O-ring. Chevy dealer charged me 8 bucks for it.
again thanks for the good info on the thread
cheers
