The fuel pressure regulator in a 2007 Chevrolet 1500 is located on the driver's side of the engine. It regulates the voltage going to the pump motor to control the pressure. The regulator is part of the fuel pump assembly and is located in the gas tank.
What You'll Learn
Fuel pressure regulator location
The fuel pressure regulator in a 2007 Chevrolet 1500 is located on the driver's side of the engine compartment, usually found under the plastic shroud of the intake manifold. You may need to disconnect the vacuum line found on top of it to access it.
Some sources suggest that the fuel pressure regulator is located on the fuel pump assembly in the gas tank. This is because these trucks use an electronic fuel regulator that regulates the voltage going to the pump motor to control the pressure.
Symptoms of a faulty fuel pressure regulator include issues with firing and losing overall thrust power when accelerating, resulting in poor fuel efficiency.

Fuel pressure sensor replacement
The fuel pressure in a 2007 Chevrolet 1500 is regulated by a fuel pressure regulator, which is located on the driver's side of the engine compartment, usually under the plastic shroud of the intake manifold. It can also be found on the fuel pump assembly in the gas tank. An electronic fuel regulator regulates the voltage going to the pump motor to control the pressure.
If you need to replace the fuel pressure sensor in your 2007 Chevrolet 1500, here's a step-by-step guide to help you through the process:
- Prepare the Vehicle: Park your vehicle on a level surface and engage the parking brake. Make sure the engine is cool before starting work.
- Locate the Fuel Pressure Sensor: The fuel pressure sensor is typically located on the fuel tank or in the engine compartment. Refer to your vehicle's repair manual or seek assistance from a qualified technician if you're unsure about the sensor's location.
- Disconnect the Sensor: Before disconnecting the sensor, take note of the wiring and connector locations. Carefully disconnect the electrical connector from the sensor. You may need to lift a locking tab or slider to release the connector.
- Remove the Old Sensor: Gently rotate and tilt the sensor to break the seal. Use a small pry tool to carefully pry the sensor straight up and out of its housing. Be cautious not to damage the sensor tip or the surrounding components.
- Install the New Sensor: Insert the new sensor into the housing by pushing it straight down. Ensure it snaps securely into place. Reconnect the electrical connector, making sure it is properly aligned and locked in place.
- Clear Fault Codes: After installing the new sensor, clear any fault codes that may have triggered the check engine light. You may need a scan tool or code reader to perform this step.
- Test the System: Start the engine and check for any leaks or unusual noises. Ensure that the check engine light does not illuminate. Take the vehicle for a test drive to confirm that the sensor is functioning correctly.
The cost of replacing the fuel pressure sensor in a 2007 Chevrolet 1500 typically ranges from $275 to $322, including parts and labor. The parts usually cost around $94, while labor costs can range from $181 to $228. However, these estimates may vary depending on your location and the specific model of your vehicle.

Fuel pressure specifications
The fuel pressure regulator in your 2007 Chevrolet Silverado 1500 engine controls the amount of fuel entering the fuel injectors. The regulator is located on the driver's side of the engine, usually under the plastic shroud of the intake manifold. To access it, you may need to disconnect the vacuum line on top of it.
The fuel pressure specifications for your vehicle depend on the specific engine configuration. For the 5.3L engine, the fuel pressure should be around 44.5 psi at the fuel rail with the key on and the engine running. For the 6.0L engine, the fuel pressure specification is 55-62 psi.
If your vehicle is exhibiting symptoms such as engine misfires, stalling at idle, black spark plug electrodes, or fuel dripping from the exhaust or regulator vacuum line, it may indicate a faulty fuel pressure regulator. In such cases, it is recommended to replace the regulator as soon as possible to prevent gasoline from getting into the oil system, which could lead to more costly damages.
It is worth noting that some 2007 Chevrolet Silverado 1500 models use an electronic fuel regulator that controls the voltage going to the pump motor to adjust fuel pressure. This type of regulator may be located in the fuel pump assembly in the gas tank, rather than on the fuel rail.

Fuel pump control module
The fuel pump control module in a 2007 Chevrolet 1500 regulates the fuel pressure. This module is a separate computer that controls the pump voltage. Lower voltage means lower pressure, and the computer controls the output voltage based on the vehicle's demand. The fuel pump control module is located above the spare tire.
If you are experiencing issues with your fuel pump control module, you may need to replace it. You can purchase a replacement module from various outlets, such as AutoZone, which offers several options, including:
- Dorman OE FIX Fuel Pump Driver Module 601-132
- ACDelco Fuel Pump Driver Module 20759945
- Duralast Fuel Pump Driver Module DM103
It is important to note that the fuel pump control module must be programmed to the vehicle using a full-function scan tool capable of pass-through module programming. Failure to do so will result in the fuel pump being inoperative.

Fuel pump driver module
The fuel pump driver module (FPDM) is an important component of the fuel system in a 2007 Chevrolet 1500, as it controls the voltage going to the fuel pump motor, which in turn regulates the fuel pressure. This module is a separate computer that adjusts the output voltage based on the vehicle's demands.
The FPDM is located in the engine compartment, usually under the plastic shroud of the intake manifold on the driver's side. However, in some newer models, it may be located in the fuel pump assembly in the gas tank.
There are several FPDM products available on the market that are compatible with the 2007 Chevrolet 1500. These include:
- Dorman OE FIX Fuel Pump Driver Module 601-132
- Dorman Fuel Pump Driver Module 601-022
- ACDelco Fuel Pump Driver Module 20759945
- Duralast Fuel Pump Driver Module DM103
- Spectra Premium Fuel Pump Driver Module FD1004
It is important to note that some FPDMs require programming to function properly with the vehicle. Failure to do so may result in an inoperative fuel pump.

Frequently asked questions
The fuel pressure regulator is located on the driver's side of the engine compartment, usually under the plastic shroud of the intake manifold.
Symptoms of a faulty fuel pressure regulator include engine misfires, stalling at idle, spark plug electrodes turning black, and gas dripping out of the exhaust or in the regulator vacuum line.
The fuel pressure for the 2007 Chevrolet 1500 is 55-62 psi.
First, disconnect the vacuum line on top of the regulator. Then, remove the retaining clamp and the regulator itself. Install the new regulator, reattach the vacuum line, and apply motor oil to the O-ring for lubrication.
Some common issues include a faulty fuel pump control module, a clogged return line, or a faulty fuel pump assembly.
