Congratulations — you’ve created custom hose assembly for your vehicle.

Automotive plumbing 101 says that before you go through the trouble of installing your new hose assembly, you’ll want to pressure-test it to make sure it’s leak-free. Fortunately, Earl’s Performance offers a complete kit that makes it quick and easy to test your assembly prior to installation, saving you potential headaches down the road.

Earl’s Performance Pressure Test Kit consists of an air valve and matching plugs for sizes from -3 AN to -16 AN. That’s pretty much all the pieces and parts you need to perform a pressure test — just add compressed air or nitrogen.

So how does it work?

This instructional video capably explains.
