I was sure hoping that it would go the other way. I am wondering since the caps I sent didn't seal totally but were Ok for me as I am never(yet) into the power step & my pistons were always pulled down on the base & sealed & when you're into the power & the piston is up no more seal. dont know for sure if that is what is going on but I have an AFB coming & I will send you the stock flat covers from it & we'll see if things improve. we WILL get this resolved
