I want to have fun and make money off of family and friends. I want to buy a big old fat 4000 lb Mercedes Benz, and modify it to get what appears to be incredible fuel economy. To do this would mean hiding extra fuel onboard. I want to con these people into making a big wager with me.
I thinking;
a) front (and or rear) frame rails sealed up, and turned into fuel tanks b) tanks hidden inside frame rails or other box sections etc. b) spare tire and wheel modified to be a fuel tank c) fabricated tank fitted inside rear seat d) fabricated tank fitted on top of original fuel tank e) fabricated tanks fitted inside front fenders f) "That old water heater in the trunk? I've been meaning to get it to the steel recycler for months!"
Any ideas on how to plumb these (in a hidden manner of course)? Any ideas on other alternative hidden areas to carry fuel?
