I just got my car back from the shop. I got most of the mods in my sig installed (vortech s trim with supporting mods). I had a 03/04 Cobra tank put in and just noticed that the gas guage isnt working any more. Its stuck on a little less than 1/2 a tank. I knew something was wrong when i was beating on it and the gas gauge hadnt moved at all. I filled up 14 gallons even and the gauge still hasnt moved. The shop is closed now, and i will take it back to them, But just wondering what could be wrong and is it something simple maybe i can do?
gas/fuel guage not working

They most likely got the fuel tubes wrapped around the fuel pump's floater. Theres an L Shaped bracket on the fuel pumps that floats up and down with the fuel level, this sends a signal to the fuel gauge and then it shows ya the level. Occasionally when installing pumps people accidently get the floater hung up in the fuel hoses. Sounds like thats what happened to you.
On the doing it yourself part? Sure, you could do it. You'll need the car jacked up and on stands, and a jack underneath the gas tank. 3 bolts hold the tank up with the metal straps. Only one strap comes down the other is hinged. Support the weight of the tank with the jack (easier when it's not full, and slowly lower it. Theres a round cover in the top center of the tank with a bunch of small bolts on it. Unbolt those and pull the cover off. Be careful not to loose any of the bolts or drop them in the tank. Also, the fumes will be overpowering. Make sure you have plenty of fresh air and dont put your face directly in there if your huffing and puffing. Pull the pumps out, taking care not to bend the floater and then reseat it. Should be fine after that. However, since you paid to have a job done... I'd take it to them to correct thier mistake. Otherwise they can say you messed it up further by doing it yourself if something still isn't right and will charge ya for the parts to correct it.

Yeah, sounds like something i'll take back into the shop and have them fix. Not worth the hassle when they will do it for free.
Here is a little more info on the problem since i have been driving it around. While i drive around, every 20 minutes or so, the gas guage needle drops waaay to the left of Empty and and the low fuel light comes on. Then after 5 minutes of it like that, it pops back up to half way mark. And neither are in the right position because i just filled up the tank totally full. It makes me think that maybe its not the float and maybe an electrical problem.
