I am (slowly) building a Great Planes P-51 with an OS 46FX
engine. I am using a Slimline Pitts-style muffler, so the
engine will be mostly enclosed except for cooling holes.
This is the first cowled plane I have built, so I'm on new
ground here. The otherwise good Great Planes instructions
aren't telling me what I need to know.
So I'll throw this to the 'Net wizards. I was planning to use
a Du-Bro #334 Kwik-Fill fuel valve on the side of the fuselage
near the fuel tank. I assume that will let me refuel without
pulling any fuel lines off the engine or muffler. But what
happens when the tank is full? Normally, I am used to seeing
the fuel line to the engine (which is pulled off during fueling),
spit fuel when the tank is full. How should this work now?
Do I need to run a tank vent line down and out the bottom of
the fuselage? Is that a third line coming out of the tank?
As you can see, I'm stuck here. I'd appreciate any help you
can provide. An e-mail directly to me would be the best way to
