I am pondering where to route the overflow tube from the engine driven fuel pump on my IO-540. As I understand this, the purpose of the overflow is to have a place for the fuel to go if the diaphragm starts to leak.
Obviously it would be a bad idea to route it out the cowling exit - the exhaust could ignite the fuel while in flight and I would have a bad day! I was thinking of sending it down the gear leg inside the fairing, but would want to provide an exit before it reached the brake as a fire could start upon landing when using the brakes. Not as bad as a fire in flight, but I prefer no fire at all!
Where did you route your overflow tube from your engine driven fuel pump?
