Kohler KT735 No Pulse For Pump?

I have a Kohler KT735-3077, 26 hp engine that has just about 100 hours on it. A mouse chewed through one of the plug wires and while waiting for the replacement ignition module, I decided to do some maintenance. The "maintenance" kit included a new pulsp fuel pump which I put on and (unwisely) threw the original one away. I also changed the oil, filter, and plugs. Now 2 pumps later I still do not have fuel coming out of the fuel pump but neither can I detect "pulsing" from the crankcase rubber hose while cranking. The trash has come and gone so I do not have the original fuel pump from when it was running.

I took the ZT to the local shop and they are telling me 3 weeks just to look at it and I have to believe this should be something simple. Any thoughts on how to "test" that there is pulse pressure from the engine?

You had mice in the engine, did you replace the ruber pulse line for the pump? Hold a tissue over the end and crank it over and see if it will move the tissue. The pulse out of motor is not much of a signal for lack of better term. Check fuel flow through the tank to motor and maybe add a temporary gravity fuel tank and bypass fuel pump.
