I have a 500 gallon fuel trailer housed in a Wells Cargo single axel van covered trailer. I am through needing it for storing gasoline. It has a 12 volt, 15 GPM fuel pump with 20 foot hose and nozzle. It has a large spin on fuel filter and a flow meter that reads gallons delivered. I have the tank plumed as a non vented tank and a 3 inch+ diameter pressure gage on the tank. The trailer is white and vented and the tank is also painted white and non vented. I have never seen the pressure go above 2 PSI during the summer with the trailer parked outside. With all being painted white the interior of the trailer stays cool. The fuel, car gas or 100LL, will keep fresh for long periods of time since no part of the fuel is lost due to vaporization. The rig makes a perfect fuel storage system parked on your ranch or airstrip while you have the nearest fuel dealer deliver to the tank. There has never been any gasoline with alcohol in the tank, only pure auto gasoline I used in my G35 V tail and my 8E Luscombe. The trailer is located in Reno, Nevada and priced at $5200. I have pictures that I will send if contacted by Email.
