Need to know by tomorrow! Is this the right float?

Im not sure of any info on it. That is just what the guy told me. It is $12 thats all I know on it.
I went ahead and ordered one from napa. Im supposed to call on tuesday next week to see if it came in.
I started the car up yesterday, and it ran really good. It stalled twice. It had some trouble restarting though after stalling or turning off. Took it for a 10 mile drive, and didnt have a problem.
