I drove my 1110 last weekend and now there is no fuel out of the pump. It has full tanks, and when I pull the hose off of the carb I can feel the pump building pressure. Were should I go from here?

Sorry, what you describe makes no sense!

Place a fuel pump test gauge between the pump outlet and the carburetor inlet. Standard pump output pressure for an IH mechanical fuel pump is a nominal 5.5psi, anywhere between 4.0psi and 6.0psi is just fine with the engine running at any rpm. At that pressure the delivery rate into an open container should be a minimum of 1 pint of liquid fuel in a twenty second crank cycle.
