The other advantage of the Hayes tank is you do not have to swap out the stopper for diesel use as in Sullivan and Dubro, also
that small diameter stopper will not leak you do not have a stopper with 3 pieces of brass tubing thru it to deal with either
This can be a real issue with the YS glow engines that run a high tank pressure. I only have one YS53 and use the Hayes tank
no leaks or blowing out the plug, this makes it a winner in all applications martin
