The fuel delivery module flange is a component of the fuel pump in some Ford Escape vehicles. If you are experiencing issues with your fuel pump, you may need to replace the fuel delivery module flange. This can be done by installing a fuel pressure gauge and monitoring the fuel pressure with the first turn of the key. If the pressure is slow to build, it may be an indication that the fuel pump is losing its prime.

Installing a fuel pressure gauge to monitor the fuel pressure
To replace the fuel delivery module flange, you can either find a technician with the right tools or wait a few seconds when starting to let the fuel pump pump fuel into the lines and then turn the ignition on.
To install a fuel pressure gauge to monitor the fuel pressure, you need to cut the fuel line and clamp each end of the cut line with hose clamps. Insert one open end of the fuel pressure gauge over one cut end of the fuel line. Slowly slide the hose clamp holding the sliced fuel line over the point where the fuel line has been forced onto the fuel pressure gauge. Turn the screw of the clamp in a clockwise direction to tighten it. Repeat this process with the other end of the sliced fuel line. You should now have the fuel line clamped at either end on the two openings of the fuel pressure gauge.
Fuel pressure gauges monitor the fuel pressure in your car or truck's engine to prevent damage to the fuel pump and injectors. Proper fuel pressure is vital for optimal engine operation and performance. Low fuel pressure can result in rough idling, poor performance and decreased fuel economy. High fuel pressure, when more fuel is pushed through the injectors than is required, results in a rich air-to-fuel ratio. A rich air-to-fuel ratio causes black exhaust and high emissions, which can overheat and cause damage to your fuel system.

Ensuring the pressure cycles up with the first turn of the key
To ensure the pressure cycles up with the first turn of the key, you can install a fuel pressure gauge to monitor the fuel pressure. The engine needs around 55 PSI and it should hold steady. You can also try cycling the key on and off a few times before cranking the engine to see if it starts right away. This can indicate if the fuel pump is losing its prime and the pressure is slow to build. If the pump is holding, the pressure should cycle up with the first turn of the key. You can also try waiting a few seconds when starting to let the fuel pump pump fuel into the lines and then turn the ignition on.

Replacing the fuel pump
To replace the fuel pump, you will need to access the pump, which is usually located in the fuel tank. You may need to remove the rear seat or the trunk liner to access the pump. Once you have located the pump, you will need to disconnect the electrical connector and the fuel lines. Be careful not to spill any fuel and make sure the area is well-ventilated.
Next, you will need to remove the old pump. This may require special tools, so it is recommended to consult a professional or a mechanic with the right tools. Once the old pump is removed, you can install the new pump. Make sure to connect the electrical connector and the fuel lines securely.
Finally, you will need to prime the new pump. This can be done by cycling the key on and off a few times before cranking the engine. You should also check the fuel pressure with a fuel pressure gauge to ensure it is holding steady at the correct PSI for your vehicle.
If you are experiencing issues with your fuel delivery module flange, it is possible that the fuel pump is losing its prime and the pressure is slow to build. In this case, you may need to replace the fuel pump to resolve the issue.

Frequently asked questions
If your car has starting issues, such as the fuel being delayed going from the tank to the engine, this could be a sign that your fuel delivery module flange needs replacing. You can also verify this by installing a fuel pressure gauge and monitoring the fuel pressure with the first turn of the key. The engine needs right at 55 PSI and it should hold steady.
If you cycle the key on and off a few times before cranking the engine over, and it still doesn't start right away, this could be a sign that your fuel delivery module flange is faulty. Another symptom is hearing the fuel pump kick in when you turn the key, but the engine still cranks for several seconds.
The only fixes are to find a technician with the right tool or to wait a few seconds when starting to let the fuel pump pump fuel into the lines and then turn the ignition on.
