Book says they need to go back on the same side. Hold your finger over the outlet and the hole in the head in between the barrels. Push the exit plunger down. If it comes back up it’s good. Mine will go down 1 time and that’s it.

I am replying from memory so its best to check quickserve but from what I remember you don't cover any holes? first (springs on) apply 40 psi or less shop air to inlet .....both plungers should extend ..remove springs and your just doing a quick tap on plungers ..they should spring back almost as quick as your finger your not trying to bottom them out on the tap. I had one that failed and I pulled the barrel and replace the crush washer and it passed after ...truck is still running.
