Fuel Pressure Test Cost Estimate

When a fuel pressure test is conducted, the technician will come to an understanding of where the fuel pressure drops based on finding the last place fuel pressure exists. Once the fuel pressure drop is located and pinpointed across one component, the technician will need to identify if that component is serviceable, if it is properly actuated, and if it must be cleaned, repaired, or replaced.

Replacing fuel system components responsible for loss of pressure will require depressurization of the fuel system, catching remaining fuel from the fuel lines, and using specialty fuel line disconnect tools in order to remove components from the fuel delivery system. In some cases, the fuel tank or rear seat may need to be removed, and any fuel system components between the fuel system and engine may need to be removed and replaced. When electrical components are disconnected, it is important that the battery is disconnected, so settings in the vehicle may be lost after the repair.

We recommend conducting a fuel system test after checking the fuses and relays, but before replacing components without diagnosis. This will prevent many good parts from being changed, decrease cost, and prevent frustration.

Fuel systems can lose pressure for a variety of reasons, but if the odor of fuel is evident around the vehicle or under the hood, the likely issue is a fuel leak. Vehicles with fuel leaks should never be driven, as this poses a distinct risk of fires, especially if the leak is in the engine bay.
