I am in need of a mustang expert!! ;)

i have a 1989 mustang lx, 4cyl. 2.3L. recently the gas gauge has stopped working, like if i sit on an incline it moves to the top like i have a full tank, but USUALLY it sits at 1/2 tank, constantly. Even when it's below 1/2. i have had this car for about 2 years and know my car so i know about how far i can get on $20 in gas, but it would be soo much better if my gauge worked!!! Do you think i need a whole new fuel pump, OR just a fuel tank sending unit? Please help me!!

thanks in advance!

You need either a sending unit or gauge. Based upon your post, I would imagine that you would not be able to replace either on your own. Locate a family member who is either a mechanic or knows one, to get your problem fixed.

lol thanks i have someone to do it i just wasn't sure as to what part i needed to buy!!

Don't buy a pump... it is not integrated in these cars.

Your mechanic friend should be able pinpoint the cause of the problem with multi-meter in a matter of minutes so that you're not buying parts you don't need.

Funny, I'm an engineer on fuel modules. I have no idea what you may need from 1989, but the newer cars only need a sending unit. Dropping a tank is the most expensive part.

Most likely the floats bad and u need a sending unit, however, there's also a slosh module behind the dash thats prone to needing replaced. Goodluck!
