$40 for five gallons?
Here you go Patrick http://www.nloc.net/vbforum/how-articles/130142-how-drain-fuel-tank-w-pics.html
Fontana only has the fuel for sale at certain times
Irwindale has 91, 100 (both unleaded), and 110-leaded all at the pump for credit/debit card, when you come in the main gate tech is to the left, the pumps are to the right up and around the corner, some guy will show up on a golf cart and unlock the pump box!!!!!
or hit up DMP he can get pretty much any fuel you want he just needs time to order it in!!!
