CAUTION: Before starting on any fuel service repair, ALWAYS release the fuel pressure from the system and disconnect the battery. Check your service manual for the correct procedure for releasing the fuel pressure on your vehicle and be sure to have any code information to reset your radio or alarm.

NOTE: The following was added by the mechanic members of BAT Auto Technical;
When working with gasoline in your garage, maintain adequate ventilation and MAKE SURE that any appliances will remain OFF from the time you start the job until the last vapors have been dissipated. This goes for water heaters, clothes dryers, and anything else that can ignite the vapors. Gasoline vapors are heavier than air and can travel a long way along the floor, and can be drawn by air currents to pilot lights. Having all pilot lights at least 18 inches above the floor will reduce, but not eliminate the danger. Also, never use gasoline as a parts or floor cleaner.

The vehicle is a 94 Plymouth Voyager van with a 3.3L engine. As you can see, the fuel hose connector on this vehicle is leaking. The customer was complaining of a fuel smell first thing in the morning.

We first checked the vacuum hose to the fuel pressure regulator for signs of fuel, as it is an easy check, but none was present. So we then went underneath and looked for signs of fuel. Once we got to the connector on the pressure hose, we could easily see where the problem was.

While it isn't absolutely necessary, it is good practice to replace the fuel filter when ever you do any repair to the fuel system.

After everything is re-installed, we turn the key to ON and listen for the pump to engage. Once the pump has run and shut off, we turn the key off and back on several times to make sure that the pump runs several times and check for any leaks.

Once we have confirmed that there are no leaks, we start and run the vehicle and recheck for leaks. If there are no leaks, we call the customer and let them know the leak is repaired. Oh yeah, and collect our fee, of course.
