O.K., one last thing now that you have the tank squared away-I'm not kidding here either, I do it to ALL my fuel before it ever get to a plane- Ad 2-3 drops of Armor-all (the stuff that makes the dashboard of your car all shiny and slippery) to your gallon of fuel. This will DEFINATELY stop any foaming caused by vibration. It won't hurt, or affect anything else-before they sold it with the lable armor-all, it was actually an industrial de-foaming agent. Here's a test if you don't believe me, shake your fuel jug vigorously then when you stop, it's nearly all foam for a few seconds, quickly remove the cap and dose it with 3 drops-instant de-foaming! Now put the cap back on, and shake the jug-no foam!
Caution: DO NOT USE ANY OTHER "VINYL PROTECTANT" AS I CAN'T GUARENTEE YOUR RESULTS-ONLY Armor-all.
