The filter holder is a Westwood f 100 8 spin-on can, gravity fed type. There is a Gar-Ber brand filter element (screw on can) on it. To change it out I got the Westwood f 100 10 fuel filter element. That is the only one our Home Depot stocked and the floor man told me it was "the one" for residential systems. Anyway, I can't get the Gar-Ber element off the Westbrook holder. Turned it hard in both directions and it won't budge.
This post reminds me of when my Mom asks me to open a jar.
