Can it be fixed!!!!

We are still waiting to see whats wrong with the RV... the ford place thinks its the fuel pump but don't know when they can get it fixed... We have to leave out of here, John's deployment flight is set for the 27th.... So much for getting back early to relax at home.  If we rent a car, we still have to travel another hour and half back west to get to a rental car.  that make a total of 3 hours that we wasted traveling east.  3 hours of the same route.  I hope they can fix it and get us on the road by this evening.
