Why would you want to pressure test a septic tank system? This is not recommended as most septic tanks are gravity systems and should not build up pressure. You can visually check your drop tank 5,000 - 10,000 gallons and your gray water tank 500 gallons for cracks. Make sure that all sewer line are on grade or you will have a vapor lock causing air to bubble in your toilet while draining water.
No, it means it is running. It may or may not be pumping gasoline with the proper pressure. Fuel pressure test will verify if it is working properly.
