While cleaning up my rusty fuel tank, pump, etc. I noted that the fuel cap has a small propellor like tab on the tank side center of the cap that allows shifting from a vented to non-vented condition for fording. I can't find any reference to this fuel cap feature in the -10 section on fording operation.
The question is in which position is the cap venting? The tab has something like an at rest position between two shoulders but when turned 90 degrees rides up the shoulders and centers between two indentations. In this position a spring loaded center pin is pulled outward or away from the underside of the cap. When twisted back 90 degrees the tab allows the center pint to go to a non-tensioned retracted position.
Which is what?

......IF you over fill the tank and the sun is on it, like said the fuel will expand.....IF you have a NON-vented cap and it seals nice then the fuel will push into the vent and if enough...a nice puddle forms under your truck. IF you have one of the vented caps and it over expands....fuel runs out all over the tank and again....nice puddle under the truck.
