Looking for some information about using a so called "transfer tank" only tank as a aux tank. Found the deezee alum tank in the size I'm looking for. It measurements are 59.5x9x19. 40 gallon tank. Sounds like the perferct size tank for not using up a lot of bed space. Here are some pictures of the tank. http://www.autoanything.com/GenericPages/ProductImage.aspx?ProductID=4616&GroupID=4

What makes this tank a "transfer only" tank? Couldn't I just use the drain hole from the tank to gravity feed into the stock filler neck? Using the rds install aux kit? Or what am I missing? Thanks

No one knows?

Gravity feeding is illegal. It has to be drawn out of the top of the tank.

why is gravidty feed illegal? my old rds aux tank was gravity feed.

I have one setup like that, gravity feed with a ball valve. Just keep it with fuel in it. If its empty driving will cause it to crack in the corners. had 2 go like that.
