Hello Mike and

. We are glad to have you join us here and we look forward to reading of your advenures and experiences. I am sure you will enjoy the website and forums. Good luck and keep us posted.
I had a 96 Aerbus on a Ford chassis that would vapor lock. I found that the fuel pump in the fuel tank was going bad. You may have an emergency cut off switch that in the event of an accident the power is cut off to the fuel pump. Make sure it is not tripped. The fuel pump is usually what goes on these and dropping the fuel tank is required to access it through the top of the tank.
