I'm not sure where the one in Perris is but a guy at work tells me his buddy fuels up his work vans there so I know there is one. In Murrieta off the Clinton Kieth rd exit at the Chevron next to the Mc Donald's.
The second one is located off of Murrieta Hot Springs rd I can't remember it's cross street but it's at the Shell gas station next to the Sam's club.
