Vulcan slow to fill

[jfrench64]

Guys how can I clean the fill valve on my vulcan?
my fill prob orings have small flat spots on them ,i think some shaved off when incerting prob into gun and are maybe blocking things making my gun very slow to fill now. Anyone else had this before ?
thanks for any input ?

Watched A Ernest video and took my fill port apart and just as I expected.
when I took the small screw out inside the port it was pluged with a small piece of rubber.
Working great again now
