i have a 1994 faclift ive changed the float the gauge is working but sometimes it goes all the way round, at the moment its stuck all the way round, someone told me theres an amplifyer module between the gauge and the tank-is this true help please!

 

According to the circuit diagram there is an "anti-slosh" module between the sender and the gauge. It's located in the trunk on the lefthandside behind the trim panel

 

thanks for the advice ive found the unit and i am waiting for a replacement will let you know how it goes thanks for your help
