with this being your first pump.... here are a couple pointers/tips...
If you bought a gasket set from napa or other parts store, the kit doesnt come with a new control shaft bushing. You will need to buy that separate... the old one is brass if it has never been replaced and a new one is steel.
When your putting the pump back together, keep in mind that vaseline is your friend when putting springs, hydraulic manifold, etc back together. Also, make sure that you mark things during dis assembly so you know where they go begin to reassemble.
