Those sintered ( sp? ) brass anti-foaming clunks that Dubro sells have worked fairly well for me.
You may want to give them a try.
They act as a filter too.
Yeah.. I am pretty much sold on those things. They certainly cover building/assembly mistakes..err..whatever..
I had one plane that was not doing well after about 1/3 of the tank had been consumed. It would get lean and quit. So, someone suggested getting those anti-foaming clunks.. think it may have been here on RCU, but I can't remember, it was quite some time ago. I swapped it out and the problem simply disappeared. Now, removing and replacing the tank may have had something to do with that, but I would prefer to attribute it to the anti-foaming clunk and let it go at that.

If it works, don't fix it, right?
