"With a gauge on the carb line shut the engine off and the fuel pressure should not leak back to zero in less then 2 minutes". What's that tell you?? Bob Shewman makes 2 modles of new flex hoses that are not bothered by the new gas or any gas that will come along in the future. One hose is like the standard flex hose and the other is has a check valve that works built into the hex fitting on the pump end of the flex hose. I have used these for almost 2 years on several cars and my flex hose and fuel drain back problems are history. G.M.

I'm not sure how the flex hose can drain a carburetor bowl??
