Fuel Pump issue

[bobcat1/178th]

While driving today my mutt broke down....The electric fuel pump sounded normal when I started driving then later the engine stopped...The fuel pump sounded like it was going twice as fast and when I took off the air cleaner hose to the carb a ton of fuel dumped out...When I run the pump it pushes a lot of fuel through the carb...

What is causing this? Is there some debris maybe stuck in the pump or a seal bad? Can the pump be fixed or is it prob shot?

I should add that the pump is a Gov't pump for the A1 mutt. Installed NOS 10yrs ago....

Carburetor float issue. Nothing wrong with the pump at all. You either got something stuck in the inlet needle or the float tower may have broken, ( I have seen a lot of that lately). Float could have broken. But it is not a pump issue. The pump running fast is due to no resistance at the carb, just flowing right through.

How's the NEW Zenith carb rebuild kits for sale out there?

If you are talking about the ones that Norfar sell then they are what I use in all my rebuilds. They come straight from Zenith and have the newer rubber parts in them.

Be very thorough in your inspection of the carb. From your description of your problem whatever happened happened fast and that is not the sign of a carb needing a rebuild. It is a sign of a carb that had a part break.
