[NSRCA-discussion] YS DZ operation

[John Gayer]

I have a few questions on the recommended fuel system for the DZ 
engines. I'm having occasional difficulty with a 140 DZ trying to quit 
once fuel level gets down to a half tank. I am not using either a foam 
clunk or a hopper tank currently.

1) Is a foam clunk necessary?
2) Is there an alternate source for these foam clunks? 15 dollars seem 
excessive for a tank clunk
3) If a hopper tank is used, does this eliminate the need for a foam clunk?
4) For a hopper tank, I would use a 2 ounce tank. Should a clunk be used 
or a hard pickup to the tank center? Overflow(input line from main tank) 
to top of hopper tank?

Thanks

John
