have you tried replacing the instrument panel?

i know they are fairly cheap ($50 or so) and relatively easy to diy.




a similar thing has happened to my older brother. he drives a 2004 tundra and whenever he would put the truck in gear the fuel guage would drop to empty and then when he put it in park it would shoot back up to normal.



so im not entirely sure what the exact problem could be.


maybe a relay or something?
