[QUOTE="sar4937, post: 6958, member: 191"] Actually fuel is comprised of many volatile components, some of which start to boil at as little as 160 degrees f. I do not believe that there is an actual boiling point that you can reference. As they boil off they change the makeup of the fuel and how it performs. I would recommend using a meat thermometer an checking the temperature of the liquids. Also there is no advantage to a higher octane rated fuel than what you engine compression ratio can utilize, and premium does have a lower boiling point (rvp). I would worry alittle more about the venting fumes exploding, and the flashpoint of the fuel. If the fuel is soaking up heat from the hydraulic side of the tank you would have to circulate it through a cooler and back into the fuel with some sort of a pump- dangerous! It would be better to know the temperatures involved and fix the source of the heat. I would think that you skidsteer hydraulic system was designed to run cool enough not to boil the fuel in the tank, but it would be easier to cool the hydraulic side rather than the fuel. Keep in mind that when the fuel hits it's flashpoint it will spontaneously combust when air is added. If your fuel system recirculates fuel back to the tank make sure that your fuel lines are not laying against the exhaust system as the heat will be introduced that way.
