Hello stovefriends, yesterday i turned new pumpshafts for the Enders Neptun type 309/312. Original it's the same mistake like at optimus 155 stove, the o-ring pump is not the burner;-) Look there. Have a nice weekend Markus(RJ)
Hello Backview, the pump tube Diameter is the same like at 9060/9061. That`s the reason for the new shaft, using the good old leather;-) I´m not a friend of O-Ring pumps, what o-ring is ever inside... Markus
Hi @Russenjesus ! I'm fixing an Enders Neptune, and I bored this O-ring pumps. I take note of your trick
