GT 200 fuel pump

[yoboat]

I’m having some trouble finding a fuel pump repair kit for my outboard. It’s a GT 200 hp Johnson 1992. My model number is VJ200SLENS. Can anyone help me with this?

Check out the maxrules web site. They ID them pretty well.

I want to replace the diaphragm, but I’m not sure the part number for it. I’ve really struggled to find a diagram that shows it my motor stops after several minutes of running, so I want to start by replacing several items fuel related.

Air motor diaphragm or fuel piston flapper ?

Both? I assume if we have it apart I should probably replace both or do you think I should be looking in a different direction? The boat has been sitting for at least nine months to a year.

It runs for about 30 seconds then stops. Then I prime the bulb again and repeat the process.

Have you tested with a portable fuel tank and another hose?-----You can likely make the fuel piston flapper.-----Are the check valves in air motor body working ?-----Is there a PRESSURE pulse from the crankcase ?

That’s a language I don’t understand. All I know is to replace parts until it works lol. How do I check for a pressure pulse?
