I just did my SR5 gauge cluster upgrade on my '88 4Runner. It seemed like everything was going well untill I filled up my gas tank. THe fuel gauge went to full, but now I've driven over 70 miles and it still reads full. It also stays at full even when the truck is off. Any ideas what could eb wrong? It worked perfectly fine with my old cluster. Maybe the needle is stuck? Any help is much appreciated. Thanks guys.

 

Did the same, mine doesnt show any fuel use for 60 miles or so. I guess it depends on the tank size the gauge was used in. Give it 150 miles, if it doesnt move, maybe it can be adjusted? THey stay up and don't drop down when engine is off.

 

yeah my 85 was sr5 and it never went down, it scares me in my 89 runner though
