The 4Runners I've owned haven't really needed much. Just replaced the steering rack on my training truck in NC. But I do remember having a fuel issue on my 5 speed truck that I sold last year. I remember it having a vent clogged causing gas vapors/smell, but I ended up replacing a fuel filter, pump and some lines as it was a bit rusty. I don't remember the codes it was throwing though. Not sure if the late trucks in the gen had different evaps though.
Thanks sir. The 01 and 02's have check valves on the top of the tank that go bad and I was hoping I could run something though it (seafoam in the tank and/or 89) or do something simple like replace the fuel filter to fix it. I don't want to drop the tank, in fact I'll take it to the dealer before I do that.
