I know my MCI with an 8V-71 had almost the save air operated fuel shut off valve.

Thankyou! I'm going to give them a call on Monday.
I am also considering adding the electric unit. What kind would I need? Would I want the have its "relaxed" or "non powered" position be retracted so when the button is pushed it extends and shuts down the bus or one that its relaxed position is extended, power applied and it retracts to let the engine run then extends to its relaxed position to shut down? I hope that made sense.
Would one way or the other be better? I'm thinking the former would be best because it only has to be used briefly to stop the motor. Would it wear out faster always having power while to motor is running?
Thank you all for that info and the funny cartoons!!
