Best Customer Service & Business Ever!

I searched everywhere for a auxiliary fuel tank and everyone was stock out with a lead time of a month plus before getting tank.

My wife found Elite and not only did I get me tank within 4days I got a bigger tank 90gallons vs a 51 gallons and the 90gallon was cheaper & came with free shipping !

Thanks to these guys I’m full speed on interstate not having to stop every 200 pluses miles!
