How much does it cost to fix a fuel pump on an 86 bronco?

an 86 Bronco should be carburated and not fuel injected,............fuel injected has an electic fuel pump mounted in the fuel tank and they are expensive to replace,........carberated has a cam driven fuel pump mounted on the engine and they are much cheaper,......cheaper for the pump,and cheaper labor because there is only 2 bolts a one clamp to replace it,,..........shouldn't take more than about 15 minutes to replace the pump on the motor.
