Funny you should ask.... I have 350 hours on my 320 and am now on my 3rd
dump valve. The part is a $6.95 hardware store item, so what can we expect.
When my 2nd one failed,I remember reading about someone that had made a
post about one of much higher quality and also higher pressure rating. I
tracked it down, purchased it for about $25.00 (I think), installed it in
no time at all since I am now expert at the process and lo and behold, It
turned out to be no better than the $6.95 hardware store part.In my
infinate wisdom, I have accepted this as a maintanance item, keep one on
hand and just swap it out when the burping starts. Life can be simple if
you just don"t fight it to much.Sincerely Fred N9BF (Don't fly like my
