> During the process of changing the fuel tank and generally replacing all the fuel lines one of the nipples on my expansion tanks broke. The nipple was so well wedged into the expansion tank hose that I had to cut 1" off the end as I couldnt get the old nipple out. Apparently I needed that inch, and now I have the new rollover float valve my expansion tank hose is not long enough.
> Anyone know the specs on that expansion tank hose? Seems quite hard and plastic like. Not the same as the other fuel line hoses.
