1988 Ford Bronco fuel pumps

You should have one on the rail, and the other in the tank. Also the pressure regulaor may need to be replaced, on the driver's side of the motor, in the back. When you turn your key on, your pump should build pressure for a few seconds, then shut off. You can hear each one, while leaning in behind front tire and then in the back at tank. You should also check fuel filter.
