Review on Advanced ABN Fuel Injection Pressure Test Kit – Enhanced Universal Set with Upgraded Flex Hoses, Fittings, and Detailed Instructions by Ryan Pollock

Initially the gauge read 0 pressure in my fuel line because the Schrader valve stem at the end of the gauge hose was fully screwed in and reaching not the stem schrader valve on my jeep grand cherokee's fuel rail. I unscrewed the valve stem from the end of the gauge hose with needle nose pliers until it came loose. Then I reinstalled it in just 2 or 3 full turns and voila it worked great, 49psi, exact specs for a jeep. Although it doesn't have a fuel drain hose, a tissue wrapped around the valve works great. All in all a great price and the case is a huge bonus. Featured!
