Recently I went on a drive in my stang. I did a nice long peel out right away. Looking at my gas gauge it was on E. I had just filled it full the week before. After checking the whole fuel line for leaks I didn't discover any. Turned on the car a half hour later the gauge was 1/4 full and slowly worked its way up to full. I mean it was slow. Has anyone had this happen to anyone, and does anyone know why it happened?

 

Happened to me when I ran some Arco gas in my car. Put some Seafoam in it, and switched back to Chevron. No more problem.

 

It could also be your cluster going bad , a lot of us have had it happen and it affects different gauges. I replaced my whole cluster with a GT500 , but others have just replaced the stepper motor for the gauge that was bad. Do a search on the forum "gauge stepper motor" ...

 

How much is the GT500 cluster?

 

ive had trouble with my gas gauge for two years. occasionally ive had trouble with my RPM needle but thats about it on mine

 

Actually it was about the same price as a GT cluster. I got it at Tousley Ford and I don't remember what I paid for it , but do a search for them on the forum and you'll find info on the GT500 cluster and it's price ...

 

Sounds like the stepper motors on your gauges are going bad. Some of my gauges started acting strange. ordered some stepper motors off ebay and fixed it for a lot less than the dealership wants for a new instrument panel.
