Morning!

The fuel gauge has been reading wonky. Never went above 3/4 even when it's full - and didn't drop below 1/4. So, I did the "clean the wires on the sender" project. The readings changed a bit, but not a lot-it did go to "empty" when I slid the float all the way down - but won't go above 3/4 (actually a bit above 3/4). I had the cluster out to do LED's a bit ago, and cleaned all the contacts there. Next step is the ground? Which one grounds the cluster? I have cleaned the grounds behind the receiver/drier, and up on top of the fender in the recent past. Gauge itself isn't happy?

 

I have done all of the above on my 87NA and when full, it still reads somewhere just above 3/4. I just marked it down to quirk of the car and moved on.

 

Check proper gauge operation on Clark's Garage.

 

Mine bounces in time with the indicator lights when they're on

 

these might help

 

This thread, or the one it links to, might be of some help.
