As I remember ERC has two unleaded fuels at Bonneville -- 100 and 104 "MUL-B". Rick can fill your tank or a gas container and seal either one. If you have a can sealed, remember that you are allowed to open the seal for fueling your race vehicle only when you've got an official watching you - so he can certify that everything was sealed before you began the refueling, and then can reseal the things after you're done. We had to go through all of that rigamarole when we were racing the little 250 bike with a 3 quart fuel tank - which is not enough for two runs. Worse - we qualified at WoS one time and the weather was going bad. When we got back to the start line/tech area, headed for the fuel truck, Jim Burkdoll told us to get right back in line to run the back up run. "We need fuel", we told him -- and then the merriment began to get us some gas and back in line before the rain hit. We made it - and the trophy is on the mantle.
