You may want to check in the 89-95 pickup/hilux forum here: http://www.toyotanation.com/forum/forumdisplay.php?f=80I have a 92 truck with 3.0 v6. Gauge is bad. Looking for independent gauge/sending unit but the sending unit threads are very small. Everything found is much larger.
It's likley any of the pickups and 4runners from 89-95 with the 3.0 will have it as well. There are a few 3.0 T100s around, but they are probbaly more scarce than the pickups! The last time I was in a slavage yard I saw a number of 4Runners with the 3.0. You can also try www.car-part.com. I don't know if their parts list gets that detailed, though.Thought about that but wasn't to sure what my odds of finding a 1992 would be. Will give it a try. Thanks!
