Subject: [FlyRotary] Re: Sump tank
I am planning on having the fuel lines go
from both tanks to the fuel selector valve, then to the fuel sump, then to the
pump, then to the fuel rail, injectors, and finally to the fuel pressure
regulator. After that, is it best to have the unused fuel go back into the
approximately 2 gallon fuel sump, or directly back to one of the fuel strake
tanks?
If you're going to have a 2 gallon fuel sump anyway, I'd
return the fuel to it. Do you actually need the sump for some
other reason? If not, you could eliminate it, and run the fuel back
to one or both tanks.
Cheers,

Hi, Rusty and thanks for the response. I have been
wondering if I really even need a sump tank. I know that Velocity Aircraft
uses one in their aircraft, so I just figured they know a lot more about these
canards than I do. It would, however be nice to totally eliminate a sump tank
and just run the return back to say, the left fuel strake. My fuel
pick-up is very close to the bottom of the tank, to the rear, so it would work
fine in climb attitudes when low on fuel. Only when the nose is pointed down
might I have a problem picking up fuel in a low fuel condition. However,
in my 31 years of military and civilian flying, I pride myself in never
allowing myself to get in a low fuel situation. I am a firm believer that air
in the tanks make no contribution to maintaining straight and level
flight. Thanks again. Paul
