Just got home after 4 months of being overseas. My fuel gauge is pegged at full. Wondering if I can use the following Sending unit from summit. GM don't make them for a 1984 camaro anymore . The Part number is as follows: SUM-290260
Thanks

i dont think its the sending unit.... i was so close to ordering the unit for my car cuz my fuel guage didnt work either, however i took off the dash and replaced the guage with a junker one, and for some reason it worked! I guess maybe the old guage died, or had a short or something.... Just a little tip to save you a hell of a lot of time!
Your best course of action would be to go to a junkyard and snag an extra fuel gauge, and a sending unit. I've had the gauge go bad before too, and I've also had the sending unit crap out as well, so it's a 50/50 shot as to which one is bad. I totally agree with Gibson though, that trying to replace the fuel gauge first is the best way to go about it. It's nothing to change the guage compared to dropping the tank! I know because I ended up going through the hell of dropping the tank to replace the sending unit, only to find out that the damn gauge was the only problem! I suppose you could try that one from Summit if it ends up being your sending unit, but I prefer to stick with a factory sender personally. The last time I replaced mine with another used one, as soon as I had the tank back in place, I plugged the harness in, hooked up the fuel lines, then turned the key on to make sure it was working good. It's good to check it before you spend a couple of hours putting everything back together just to find out you've got another bad sender. Just my .02.

Rotate the retainer ring counterclockwise about 1/8 turn or so, remove, reverse procedure. Very very simple, doesn't take more than about 2 minutes.
The tank of course needs to be out of the car in order to do this.

Roughly paraphrased into modern English, and applied to figuring out what's wrong with your car:
The simplest explanation that fits all the facts is probably the right one.
extremely hard! There is alot of clutter in the way, youll have to move it, youll have to jack the car up alot!, youll also have to empty the fuel tank, and of course, the number 1 thing, disconnect the battery...
