Thanks for all the great replies to my origional question guys. I tried using a piece of stiff tubing in the middle of the clunk line but found that it made things a little "too stiff". The clunk did not want to move freely. This might be attributed to the fact that the tank is not too huge, about 10 ounces. I would up (so far!) using a three line setup (with 2 clunks) and using standard blue silicone tubing on both clunks. They move freely around the rear of the tank area and I could not possibly get them to kink and go to the front part of the tank. It's sure something to keep an eye on after a crash or if the blue tubing gets more flexible under other conditions.

Gee whiz, it never did occur to me that the black tubing sometimes included with tank kits was for gasoline ONLY! Gulp, maybe I have used it.....

Thanks again,

Ernie
