What Are Legal Implications Of Home Built Transfer Fuel Tank

[tlukasavige172]

I have some questions about building my own pickup bed fuel transfer tank. It will hold unleaded gas for the toys when we take them out (motorcycles and snowmobiles). It will not be plumed into my vehicle fuel system and will be a stand along tank with its own transfer pump.

Does anyone know how legal this is? I have a custom made toy hauler from a company in Indiana and don't see any kind of markings on the fuel tank that is on the trailer (onboard fueling system). What do trailer manufacturers have to abide by for their tanks? Thanks for any advice.

I'd call your State Department of Transportation or State Patrol, they should be able to answer your question, quote the regulation or tell you who to speak with.

You can check with a company who used to build gas tanks for some of the trailer manufactures.

There are a lot of recent regulations (since 2004) that limit the fuel evaporation from fuel tanks. Before 2002, allowing 1 ounce of fuel evaporation per 24 hours was acceptable, however by 2005 Ford had to change their fuel system to meet a less than 10 grams per 24 hour fuel vapor loss. There are 28 grams in 1 ounce. So they can not even have a fuel vapor recovery tank, as it can allow some vapors out of the tank when it is warm out.
