got a problem with broken fuel gauge
 

hey everyone, im not the brightest at cars but im not the most stupidest either.. igot a 1987 Mustang LX two door. not bad for paying 500. looks good, runs good, just a few minor problems. the main concern is the fuel gauge its not working. i dont kwno where to start. either the gas floater. or a fuse for the gauge, i think i did try the fuse and couldnt find anything concerning the fuel other than the locking gas cap. anyone able to help before i send in to shop ? let me know email is punkbythebook12@yahoo.com or leave a reply thanks
