Fuel Pressure Testers for Fuel Injection and Low-Pressure Systems

Check fuel pressure, pre-feed pressure, and fuel supply! A reliable fuel supply is essential for the fuel injection system and high-pressure pump to function properly.

Depending on the meter, vehicle, and connection, Autotestgeräte Leitenberger’s fuel pressure testers can be used to check, among other things, pre-feed pressure, system pressure, the inlet pressure of a high-pressure pump, as well as pressure and vacuum in the low-pressure range.

Analog and digital diagnostic kits with various adapters enable use on numerous gasoline and diesel vehicles. Transparent test lines or test blocks also allow for visual inspection of the fuel flow for air bubbles when used with compatible devices.

Special high-pressure testers are also available for gasoline direct injection systems (GDI). Technically, these differ from conventional low-pressure testers and from common-rail high-pressure testers for diesel systems.

The permissible pressures and connection points always depend on the vehicle, the injection system, and the manufacturer’s specifications.
