Can someone tell my how to change the primer pump?
Is there a hidden pin or anything,or does it just screw off.Also what tool is used? Thanks,Georgia

The hand pump just screws on to the injector pump. The base of the pump is hexagonal, and can be removed if you have a crowsfoot wrench to reach it. I didn't, so I used a pair of vise grips to grip the barrel of the pump to remove it.

I mounted the new hand pump similarly, except I wrapped the new barrel with a cloth to prevent scratches. No visible leaks.
