Dan,
The electric fuel pump is under the seat, so fuel lines go from the tank to the pump under the seat and back to the engine

Not a player in this debate, but curious just the same.



I'm trying to visualize where the fuel tank is that requires routing
fuel lines under the seat pan to get to the engine bay.* The engine
bay is aft of the wing, isn't it?* Where's the fuel carried?

Bert, a fuel line snagged when the prop was extended.
Fuel leaked into the engine compartment.
The extinguisher was in the car at the side of the runway.

Schleicher has since changed their fuel line material. Schempp might still be using lines that are not aviation grade. They are not aviation grade on my club's Duo XT. Don't know about others.

TW, your fuel lines likely go through the engine compartment. After a leak a retracted engine could cause a fire.

Jim,
the holes in my engine bay wall are covered with stainless steel mesh which would prevent flames leaking into the cockpit during the few minutes (seconds?)the engine bay wall hasn't burnt down (the expoxy burns quite well, and it's not even a sandwich structure), or the fire hasn't extended via the fuel lines which run underneath the seat pan.

And - if I specifically ask an engineer from Schempp-Hirth whether it's ok to drill these holes, and he tells me to go ahead, I tend to believe that he knows about the wall.

Cheers
Bert
(yes, TW's name is also Bert ;-))
