I've had the gas fume problem since I've owned the Cruiser - about 6 years now. It seems like it's getting worse, so I figure it's time to dive in and see what I can do to fix it. Last week I took the family camping. There are 6 of us and I pull a small trailer for all of our stuff. It was warmish (80s) and we went over a 10k ft pass here in CO. The combination of all those factors and the fumes and gas tank pressure was horrible. I was ready to start working through the EVAP system, replacing parts, but after reading much on this site especially @2001LC's work and thoughts, I figured I needed to take a more holistic approach.
First step is recording some OBD2 logs driving around today - OAT was probably 80ish. After I got home from the logged drive there was a bit of tank pressure - probably took 3-5 seconds to release after unscrewing the gas cap. This drive wasn't necessarily intended to produce the problem, but more as a starting point to identify how the Cruiser is running. From my limited understanding, I have a fuel trim problem in 3 and 4. I'm hoping @2001LC will take a look at the logs and tell me what you think?
OBD2 Logs (not sure how to post this link without the giant preview)
Helpful thread:
Vehicle Info:
2000 Land Cruiser
207k miles
Aftermarket front bumper
Full belly skids
Rock Sliders
Rear bumper
Some maintenance history:
Original radiator
TB/WP service completed 3/30/19 at 197k
new coils and plugs installed 3/2019 at 197k
At some point I sprayed out the radiators - they weren't too bad (may be time to try that again)

Gas tank building excessive pressure & fuel smell. Dangerous for sure! Why does this happen?
DANGEROUS GAS PRESSURE BUILD UP IN GAS TANK! Why? What's going on? How can we fix this? Edited 12/29/23: It is a unban myth, all Land Cruisers boil fuel. They do not! Edited 7/4/20: What I found in every case of "fuel boiling" I've worked on. Was, engine overheating or running hot. :hmm: That...
