Review on Spectra Premium FN850 Fuel Filler by Bryan Hill

Filler looked great when I bought it and installed it. However, this morning I filled up the van and couldn't get the fuel pump injector out of the filler neck. As soon as I did this (after about a minute), I found that the check valve flapper inside the filler neck had separated from the filler neck. More Chinese junk. It remains to be hoped that the manufacturer will eliminate this shortcoming.
