So some folks want to know what magic lives inside a 3B lift pump. I imagine many lift pumps function like this one in the 80s. Just glancing over at my 4bd1t and its lift pump closely resembles it.
The pump is held onto the engine by 3 bolts. It's actuated by a lobe on the injection pump shaft.
The priming pump which gives so many folks problems uses a 24mm wrench to unscrew it or you can gently use vice grips instead. It is easily crushed I imagine. It's thin metal.
This is what you find under the priming pump. A spring and a seal. The seal can be replaced.
