Daughter heads back to college today, and I've got a "wait" before her flight, so I decided to jump sequence on projects and rebuild a lift pump. There's a number of threads on the topic, and Stretch did his usual fantastic job documenting the build on the "M" pump / non turbo / 2 dog ear'd lift pump.
This covers the 3 dog ear'd pump found on the "MW" pump -- and yes, the turbo engine is nearing completion. I could not find anything on the rebuild, so this is how I did it.
Overall, this is a really easy project. I would say collectively an hour for everything. No special tools, except a dental pick. I would venture a guess that this is something which should be done every 10 years. The kit costs $6 bucks, and the O rings are pretty cheap too. Not pictured is the gasket to mate the lift pump back to the IP and the black handled Bosch primer pump. Both of those are under $20.
The starting point is clean parts. I would say there was around a table spoon of goo, rust crap, and other stuff inside the body of the lift pump. This was a JY IP with lift pump so I am not surprised. It took a full 50 minute cycle in the ultrasonic cleaner to clean it up.
Here are some pictures.
The parts
The kit
The "head" -- not sure the technical name, but it's the part which goes inside the IP
And the "O" ring. The old "O" ring is picked out and the new one is pushed in. I used a phillips head screwdriver to glide it into the grove. The steel pushrod goes in after the "O" ring is inserted. The "O" ring fits inside a grove which is about impossible to take a picture of. There was a noticable difference in pull or drag on the push rod after the new "O" ring was installed.
