Thank you all for the info. I will look for a vent line coming from the top of the tank to a vapor recovery canister. Being that my Bounder is a 1995 Ford chassis I wonder if it would have a vapor recovery unit. I can tell you all that there is no leaks of gas under the rig and 3/4 of a gallon is no big deal except for it is 3/4 of a gallon every week ! It adds up !
How long do you let it sit between uses? Trying filling it up and then just leave it alone for however long you can then see how much is missing. I'll bet no matter how long you leave it you'll find it takes 3/4 of a gallon every time to top it off because that's how much goes out the overflow. Once that 3/4 is gone, it will maintain that level.
