Frederick, Md		I know something isn’t right, because I’ve pumped atleast 100x and it’s never taken this long, however the primer seems to build pressure if I close the bleeder and pump. (I could hear fuel moving to the tank)

I will fill the tank, if no difference I’ll remove the primer and inspect. Easy day in the shop went to crap quick.
