smoke syst

What pump are you using on your home brew smoke system. I am building one and bought the pump the smoking airplane guy uses and it puts out 60 psi. The selonoid is rated at 25 psi. I called the pump manufacturer and they said not to pump oil with that pump so I am planning to change to a facet fuel pump 6psi. What is the pressure of your pump?

Thanks
