Sounds like you have the correct hose, and yes, you check with the engine not running.
There is a rubber diaphragm inside the FPR that moves up and done with high and low vacuum, which in turn opens and closes a valve that regulates fuel flow. If that diaphragm develops a tear, gas is sucked directly into the vacuum hose and into the intake system. That is why you smell gas in the vacuum hose.
Replace the FPR.
