Is changing the o-rings and lubing the pump an owner/operator maintenance item or is that work to be done by an A&P? Haven't flown in a month and today the primer just slid in and out with zero resistance and I am suspecting seals are bad. After several strokes it started to grab fuel here and there but never really got tight. It was a bear to get the engine fired but once it did everything ran normal. Post flight at the fuel pumps revealed no change in how the primer feels so thinking a rebuild is in order.
