brown

Brown? Tha package came with white and black. The problem is I have lost the package with th einformation. And that was sometime back.

Dubro gas stoppers are brown... Sullivan gas stoppers appear to be black (from looking at the Sullivan part numbers on Tower Hobbies website)...

Uhhh, I hate to be the one to say this, but some really expensive experience has indicated that you should go with the Dubro brown stopper. I hate being "cryptic" again but I can't say more.

Ok guys. Thanks for the info. The Sullivan one is black for gas. Don't have the Dubro one. Will pay close attention to the black one from Sullivan.

I have heard the same basic thing that Silver stated. Something about the Sullivan gas stopper turning into mush.

Now that you mention it having a black Sullivan stopper turn into mush may have (very likely) happened to me... Last year I noticed that the stopper in the Sullivan tank in my 29% Aeroworks Edge 540 had turned to mush. Fortunately I just happened to catch this problem before any damage was done because of another issue... I bought this plane from an experienced builder/pilot and I remember thinking it was odd that he would have mistakenly used a glow fuel stopper... I've since replaced with a Dubro tank and brown gas stopper... Azhar -- you should seriously consider getting a brown Dubro stopper...
