Review on Lang Tools TU 32 21 Compucheck Restriction by Aaron Shaw

The picture and description correspond to this measuring device. This is a vacuum gauge used to measure the restriction in the fuel supply to the fuel pump on a diesel engine. The pressure gauge includes a connector for quick connection. We didn't have to install a port as our engine already had test ports installed from the factory. The caliber is good and large which allows weak eyes like mine to read it accurately. The meter is well protected by an additional rubber-like device that surrounds the side of the meter. The hitch works as it should, hitching/unhitching without any drops. This sensor allows us to quickly check the condition of the fuel filter and check for clogs in the fuel supply line.
