Fuel System Leak F150

I have a Ford F150 1992 that is leaking from the fuel system. Ford Consumer Hotline reports that a recall was performed, but has no record of a date, only a dealership. Dealership has no record of performing recall. In any event, whether it was performed or not, the check valve has gone out again. To me this is a serious safety issue. NHTSA has an open investigation in regards to this recall. Has anyone been in this same situation? Ford said to contact them if it catches on fire!
