(your wasting your time unless you have 5. you wont find it as I guarantee in your situation its more than one. Did you check the barrel and plunger orings and sealing washers? the check valves in the pump head?)


Ok I guess Ill have to go buy the rest as well then. I did test them by applying air to see if the plungers extended and by pushing back down on the plungers and they pop back out like they should, do i need to remove the barrel retainers to check the orings and washers? I read on quick serve i have to replace the barrel retainers if I removed them.
