Hi Marko--it sounds like you are well purged. Like Rumbleweed, I would zero in on the pump. Check the inlet side fittings between the tank and pump to make sure they are tight, not sucking in air.

Last year I swapped out the original pump for a quieter one, but saved the old one "just in case." If you don't find another cure, I could run up to Greeley and we could do a quick swap, see if that fixes the problem. Right now I'm trying to get in some final camping trips before the snow is gone, but anytime after that.

You can pm or email me.
