How difficult is it to repair the fuel primer on a 2004 silverado diesel? on 2004 Chevrolet Silverado 2500 HD

If I take out the 2 screws from the coverplate, what can I expect? The last time I ran out of fuel, the primer wouldn't reprime the engine until I pushed it extremely hard. Only the last eighth inch of movement produced any pumping action. Can the seals or the valves be replaced or renewed in it? The dealer says the entire assy. comes as a unit.
