Detailed Description
The Standard Ignition PR500 fuel injection pressure regulator helps maintain the fuel pressure required by the injection system on select Audi Q7 and Volkswagen Touareg applications. As a return-style regulator, it manages excess fuel flow back through the return circuit to support stable fuel delivery under changing engine demand. This part cross-references Gates 24208 for the same application.
Compatible With 2007-2012 Audi Q7 and 2009-2010 Volkswagen Touareg, the PR500 is an adjustable replacement option for gas-powered fuel injection systems. Use Standard Ignition PR500 when servicing a fuel pressure regulator on these vehicles and when a return-type layout is required.
Common Issues This Part May Address
- Fuel pressure that is too high or too low at the rail
- Hard starting caused by unstable fuel delivery
- Rough idle related to inconsistent injector pressure
- Fuel system performance problems on return-style setups
- Pressure regulation faults in select Audi Q7 and Volkswagen Touareg models
Installation Notes and Tips
Verify the vehicle uses a gas return-type fuel system before installation. Confirm inlet and outlet routing, and compare the original regulator configuration to the PR500 before removal. Because this regulator is adjustable, final setup should follow the vehicle service procedure and fuel pressure specification for the application.
