Re: Extra fuel vent vs another pump
Peter,
As previously stated, my 5/8" return line is at the very top of the header with the 3/16"? vent tube bent into the top of it. The fuel in header is consistantly 1-1/2" below that level when full. The only time that was not the case was when I mistakenly added fuel from the aux tank into two already full tanks. That was complete stupidity and lack of fuel management on my part. But I got distracted and it happened to me. It can happen to others with similar setups. Other than that *&%$UP, I have not experienced a problem with it in 600 hours that I am aware of. Will make some pictures available in a little while. Regards, Jim P.

When the main is full then during turbulence it has nowhere else to go but up the return pipe, and into the vent.And with the filler setup you have then the return pipe will in fact be filled to begin. Not good for supply to the carb.filling from the top (mine is different than stock, 5 gallon header tankis on pax side only) into the header allows me to fill the main and1/2" fill tube to the main which is about 1 1/2" from top of fuselage(can fill plane very quickly). This keeps the vent clear at all times.>------------- of Service.
