North Texas Karters

I have a pair of rotax karts. I was told to avoid running normal pump gas in them (ethanol messes up the jetting and can lead up to killing the engine) and to stick wiht VPRacing Fuel MS93.
Besides driving all the way back to DKC (sorry guys - it's a long friggin drive) are there other places for me to get this stuff?
I've heard that Motorsport Sales has it, but they don't answer the phone and it's still a long drive.

Specicaally looking for a source around Lewisville or Denton.

TIA

how much do you need to buy and when ? call me at 214 357 0545 or cell 214 542 7700

I managed some MS103 from Bates which the karts appear to like pretty well. However, we ran through the entire 5 gallon jug yesterday so I'll need more for next time.
