fuel tank system question

This may come accross as a foolish question but I have a leak while filling up with gas for my 92 dakota. Now my question is, the part of the filler neck that gets bolted to the bed-then goes to the rubber radiator like hose has a small leak it appears I should get get a newer one however I am not sure of the exact name for said part is it callled fuel filler vallve?

Sent you an email...I hope it goes through. Stevo
