With my onboard air system I needed a few extra parts to add a external pressure gauge and this was my answer allong with a tee fitting and a few push connect fittings and presto. It works perfectly without the use of another port on the tank and a second long air line running to the back of the truck.
Easy to install and quality made. To anyone reading this review, you should stop reading the reviews and just order it! You won't regret it!
