Stock in tank pump
 

I got a 2000 2500 and my stock pump or I guess fuel sending unit went bad does nyone know where I can find one?

If you are planning on adding a FASS/AirDOg, which is an excellent idea to keep that $1000+ injection pump alive, I would use one of these:

Modified liberty fuel module

Now is that a stock replacement? I don't need a functioning in tank pump I need the dummy pump that was in there

That will drop right in, and has the capabilities to flow lots of fuel. It doesn't come with a pump, just the level sender, basket, and connection ports.

Ok so it's just the basic fuel level sending unit

Pretty much. It's a basic unit with upgraded parts for extra flow capability.
