Fellow Cubbers,

I've noticed over the last few months a couple of fuel leaks on post flight wipe down. The first however, is the primer. If it gets one hair more than 2 primes, or any but the slowest push in it squirts out fuel onto the floor boards, or the fortunate front seater's knee. Needle valve?

The second is a daily accumulation of the blue-fuel residue dripping off the trailing edge of the bottom cowl.It doesn't leak fast enough to watch it I can only assume it's a gascolator leak, or possibly the fuel sump dripping?

Any ideas would be greatly appreciated.
