How many of us are there? Owners of Dodge based RV's?

My question to the group is does the 76 Mopar 440 carburetor have a primer pump? If you pump the foot pedal does it pump gas into the carburetor throat? It has sat for a week and now will not start. It has an electric fuel pump on it so I let the pump run for awhile before trying to start it. Last weekend we went camping and when we went to leave it was a hard start.

Update: went out and let the fuel pump run for 2 more minutes and it started right up :)
