Also lost my sub-tank yesterday. Got the warning light on the dash and it won't transfer to main.

I had a quick look at the air con problem and it looks like the TJM side step mount has rubbed through the ally aircon tube. Guess who's getting a phone call today!..haha

I traced the sub transfer pump wiring and it goes to a harness in the same spot where the aircon tube was damaged so I wonder if the harness was damaged as well .

Will have another look today
