The dealership should have provided you with a sheet detailing what symptoms you provided, what testing they conducted, what the results were, and the recommended fix. Post that info and then a better answer can be given here.
There is only one (venturi-style) fuel pump, located in the left tank. Pressure from this is used to activate a siphon pump in the right tank. Both units are pretty reliable and based on the proven, two tank Corvette design. The fuel system is a PITA to service, since the integrated sender units are in each tank, along with the fuel filter. There's a lot of interference to remove, which accounts for a higher than average labor rate. This problem could be caused by a bad sender unit, but without test result codes, it's just logical guessing on my part.
