Uh oh. Found the gas fume culprit. Rusted edge of gas tank.

Wow look at that. A new inspection I'm going to do!

Spectra makes replacement tanks: Product

It seems there should be something like JB Weld tape. 3" wide to tape across that seam and let dry.

Thats one solution, but we may be less one inmate from AL should you blow up if your vehicle gets hit ( that tape won't hold) Seriously for the price of a new tank and 3-4 hrs of your own labor to drop and swap; why F'around with tape or glue on a compromised tank.

Oh sh*^t! Keep the metal saw and welder away! Time for a new oversized tank

Build a heatshield as shown in that thread. After that the issue should disappear completely.

Which thread on building a heat shield?? I have same issue in an 04.

Thank you.

Thank you.

It's a super simple mod. Maybe I'll actually do it today now that the temps are warming up. I'm going to do the other side too to shield the AC lines.

100 Caught fire & gas tank venting concerns

Guys, i just posted this on the "Engine shutting of on long trips thread", which i started a couple of years ago...

UPDATE: I went on a fishing trip in early august. The temperatures were 90-110 the entire way. It's been an early and hot summer this year in s. california. I filled up the land cruiser with a full tank half way through the trip. There were no symptoms whatsoever. No vacuum when opening the gas cap, no hissing, no gas boiling or even smell of gas when driving. This trip had the high temp and elevation gains which has CONSISTENTLY caused the symptoms mentioned previously, but the LC experienced no such symptoms this time!

I believe there are 2 problems on these LC's, one is a charcoal canister and fuel tank vent which caused the engine to sputter and die and on 06-07 models (possibly earlier as well), need to be replaced with updated units. The second are the fuel lines run near catalytic converter causing to fuel to overheat.

Lastly, i added a heat shield near the catalytic converter to block radiant heat which caused the gas to get hot, taking off the previous temporary heat wrap i had wrapped the fuel lines in. The heat shield is 24 gauge sheetmetal, 23" by 3.5", riveted to the existing cat heat shield. I added thermotec heat shield to the sheetmetal, only because i had it laying around, i believe it is NOT necessary...

I'm posting detailed work and results on this topic because, frankly, this was a huge PITA for me and had me considering selling the LC but i believe it's solved once and for all...

Just picked up a fuel tank from an ‘05 LC at Butler Auto recycling in Pensacola. Looks to be in excellent shape. Got it for $86 and 90 day warranty.

Best practice, replace seal(s) with new OEM!

I am doing both sides this weekend too. Where are you sourcing the metal? Lowes?

For anyone who has this problem in the future, I bought the Spectra on Amazon. It came with gaskets and hardware and looked identical to the oem.
