Hi my name isXXXXX will assist you.

.

There are no fuel pump kits available for marine fuel pumps. You have to replace the pump they do this for liability reasons if the pump leaks after a rebuild it is an explosion hazard so they don't offer a kit. Have you tried running the engine on another fuel source to eliminate a restriction in the boat side fuel system?

.

As for the speedometer in the lower unit all you can do is clean the tube out. At the very front of the drive is a very small hole that gets clogged with debris. Use a very small drill bit to clear the tube then blow out from the speedo line backwards to clear the tube a hose. When using the drill bit use by hand only if you use a power drill you can drill all the way through into the oil cavity of the drive.

How do I set up and alternative fuel source, please let me know. Thinking I just might change the mechanical fuel pump too electric fuel pump what do you think of that idea
Then you have to do some plumbing add some switches and mount an electric fuel pump. That still doesn't mean thats the problem. Just get a Jerry can and some fuel hose disconnect the fuel line from the fuel filter connect the hose from the Jerry can and run the boat.
