Congratulations on your purchase of the COBB Tuning Fuel Pressure Sensor Kit. The following instructions will assist you through your installation process. Please read them first BEFORE beginning the install and familiarize yourself with the steps and tools needed. If you feel that you cannot properly perform this installation, we HIGHLY recommend you take the vehicle to a qualified and experienced automotive technician.
IMPORTANT! Installing this kit will require custom tuning or utilizing an appropriate Stage Power Package map that allows the TGV to be used for sensor input. Please consult with COBB or an authorized ProTuner in your area.
This Kit is intended to be installed in conjunction with the Cobb Flex Fuel kit for real time Fuel Pressure feedback - a safety feature required for OTS maps. Please refer to the Flex Fuel Kit page for instructions on removing the fuel lines.
Tools Needed
First off you'll need to decide where you're going to install the sensor, use the table below to find the best place for your sensor. While it can work in other positions these are where we typically recommend they get installed.

Important! Before removing your fuel line, make sure to discharge existing fuel pressure from the system. Failure to do so can result in property damage, fire, and severe burns!
The COBB Fuel Pressure Sensor installs in the lines between the intake manifold side fuel line connector and the regulator. In our example we're still using the factory regulator so we'll be installing the sensor on our feed line. Our Flex Fuel Sensor and/or Fuel Pressure sensor do not restrict fuel flow and will not cause any hindrances. It's also mandatory that you install either sensor pre-regulator, regardless of application, to ensure accurate readings. The flow of fuel is as such:
There are two locations where you can install the Fuel Pressure sensor. You can install it to A) directly to the feed line near the intake manifold, or B) onto the COBB Ethanol Content Sensor depending on our chart above.
Failure to install your fitting in the correct location can lead to damage to your vehicle or the adapter that will not be covered under warranty. |
Install the AN fitting onto either the feed or return line, it will work either way as they are both before the regulator.
Do not put any thread sealant onto the AN fitting ends, only on the pressure sensor where it installs to the fitting. |
