    Gas/Fuel vapors/fumes visible from gas door

    One at a time but yet that’s what I’d do. I don’t think I’d go the IFTTT rouge though, I’d just measure fuel temps and once I had an idea of what is/isn’t reasonable I’d look for an N.O. thermostat that could just trigger the fan on when the temp hits a certain point.

    Gas/Fuel vapors/fumes visible from gas door

    Not sure whether to "like" this or frown but yeah you definitely had a lot more boiling issues than I did on most of the trip. I'd definitely pull that fuel skid for a bit to see if it helps. Honestly if you're not going to wheel for a bit I'd be tempted to pull all of them for a week or two...

    Gas/Fuel vapors/fumes visible from gas door

    In fairness my IAT on TOTW was reading 120F. But I don't think on the 200 there's much benefit to a snorkel to reduce IAT unless you're driving as at crawl speed (or in gridlock) the airflow is so slow it seems to reach the same temps (about 20-25F hotter than actual ambient temp) by the time...

    Interesting. Skids probably influence the frequency/severity but I have Asfir skids which are thicker but barely more coverage than the factory stuff. So it's not *just* a skids/no-skids issue.

    Gas/Fuel vapors/fumes visible from gas door

    I have a snorkel since ~2017 and I boiled this time on TOTW. I've had a slight issue before but nothing like this. After that incident on this trip boiling seemed worse throughout UT/CO.

    Is there an obd fusion sensor for the fuel temp? At least 4 of the 7 of us had various boiling fuel issues today

    Gas/Fuel vapors/fumes visible from gas door

    I doubt a hood scoop will do much for you, but if you want to look cool, have at it. In practice unless you're actually channeling air into a very specific location I think you're more likely to end up creating a "high pressure" area which ends up impeding the flow of air through the radiators...

    Gas/Fuel vapors/fumes visible from gas door

    For the sheet metal issue, you could try to heat-shield the exhaust, or maybe just turn it towards the rear tire to push heat to the side. That said if the tank is flexing in an area you can access I suggest just getting a bit of U channel from Home Depot and trying to attach it to the tank...

    I’ll see if I can figure out what sensor is used to determine pressure and/or if the FSM mentions another about expected or boundary fuel pressure values somewhere in the the troubleshooting sections. The dashboard itself would be trivial to create once we know what the parameters are

    Gas/Fuel vapors/fumes visible from gas door

    My rig doesn’t run hot! :) Ok not entirely true. Took this today while going over Rabbit Ears Pass near Steamboat Springs. 9300’, 14k lbs GCWR (truck + trailer). A/T and engine oil temps get hot, but coolant stays normal at 196F. No fuel boiling out of the tank. I wish I’d used my...

    Gas/Fuel vapors/fumes visible from gas door

    Do those with built LX570’s have boiling fuel as often as those with LC’s? I’ve found if I put 87 octane in my rotopax I have to regularly vent it if the truck sits in the hot sun or it will expand a ton and then when I vent the vapors seem to be boiling. If I fill it with 93 octane I rarely...

    Gas/Fuel vapors/fumes visible from gas door

    I’ve never seen my coolant temp exceed 203F. That includes towing 6k lbs over 11k mountain passes, and through 100F+ stretches of highway at 75+. Doing trails this week I actually found it ran lower than normal when in 4Lo and in 1st or 2nd, around 185-190. Someone else in my group had high...

    Quick answer would be to carry an IR thermometer and just zap it with a laser occasionally and record the temp.

    Gas/Fuel vapors/fumes visible from gas door

    I posted this in another thread, and I've noted this before If you're seeing boiling gas, try a tank of premium. I've anecdotally found I hardly ever need to vent my rotopax when I used 93 octane from BP last year, but when I kept 87 in it the summer before I have to vent it daily. Far far...
