Extra Tank

As far as I am concerned the sun doesn't rise and set on transfer flow. RDS makes reliable tanks, fuel pumps are available at the auto parts store, and nitrile electrically operated shut off valves are available on line. So it can be done at a fraction of the transfer flow cost.

I sometimes wonder if transfer flow had Sauel do their web site. :h

I have the 100 gallon Transfer Flow in my truck bed. Per mfg. 100% legal in all states.

Gravity fed tanks (diesel) are legal in Oregon I can't speak for the rest of the country. Gravity fed Gas a no no in any state even Alaska

Check the truck stops along I5, they probably have a locking cap for the 2" pipe. They are common.

Good luck,

Fred.

I find gravity fill kits on the market like Northern. When I look into them I find them illegal. I find no powered kits when I look. I plan on reinstalling it when I get a chance. I am looking for a lockable fill cap for the tank first. It has a 2 inch pipe thread in the tank. I want to make sure is safe from someone putting something in the tank.

Perfectly legal. Many guys run them, I would but they are very expensive.

If it is legal in your home state, the others can not tell you no.

California has some of the most restrictive laws - and most gas auxiliary tanks installed after 2005 are not allowed. Diesel tanks are a little less restrictive, because they do not need to meet the less than 20 grams fuel loss per day - it can happen when gasoline evaporates and leaves the tank.

From what I hear, gravity flow tanks are not allowed. This is because in a accident, it would be possible to separate the tank from the pickup bed, and fuel line would break and dump a lot of fuel quickly. Or if the pickup overturns, it might drain fuel from the tank or it's connections. Also there might be a possibility that the gravity flow might overfill the main tank.

You do not have these problems, as you have a transfer pump, solenoid valve to stop flow when the pump is not running, and probably something to prevent the main tank from filling from the Aux tank when it is already full.

So I say keep using it. IN a gas truck, I would say if the model year where newer than say 2005 it might not pass EPA's stricter regulations.

PS: You can check the laws at Transferflow.com They also sell larger capacity diesel tanks for all the major brand trucks.
