Description: This special tool kit is designed to remove and dismantle injectors from engines such as the GM Opel SGE 3 & 4 Cylinder family of gasoline engines. This puller is required to dismantle the direct injection injectors on Opel and GM engines. These are firmly screwed to the fuel rail. Dismantling the fuel rail without special tools will damage the sensitive fuel connection pipes. It is only possible to remove all injectors together with the injection rail. Simply removing and separating the rail from the injectors is prohibited by the manufacturer and can lead to leaks.
