Had the 12.5 tank installed last week at a dedicated Land Cruiser shop. Ran the pump after it auto View attachment 3619154shut off and then filled it up. Took 11.5 gallons. Does this picture of the install look right?
I’ve had mine installed twice (move it over from one truck to another). The first time looked like yours with a gap. The second install was better looking. That gap you see doesn’t hurt anything just looks a bit ugly.
