Ever had a hi-flow fuel nozzle click out forcing you to fill up at a slower flow-rate.
There is a breather valve for both fuel tanks under the vehicle. If its blocked it will contribute to the bowser nozzle clicking out.
The valve is mounted on a bracket under the cabin in a hard-to-see spot above the rear diff. One of the small hoses coming off the rear tank goes to a Y junction. One branch goes to the main tank, the other goes to the Breather(white)&Holder(black).
Mine was clogged and difficult to clean, I replaced it with a new one.
I cut the old one open to see how it works. See pic.
It's bi-directional and is a valve inside a valve. Looks like it could easily jam open with a small amount of dust, but with lots of fine dust could just clog up, as mine did.
It can also breathe in freely if it is stuck open. So when driving thru deep water the tanks could inhale a small amount of water.
