Injector Puller Sets are found in the automotive parts section of most stores that sell auto repair tools. They are used to remove the injectors from a car engine when they need to be repaired or replaced.
Injector puller sets come with different types of pullers to remove the particular set of injectors needed. There are two kinds of injectors, the side feed and overhead feed. The side feed injectors have a single bolt in one of the corners spread out around the bottom edge of the injector and a single bolt on the top edge. The overhead injectors have a single large bolt in the middle and a large castellated nut on top. Both types have one smaller bolt on top and three or four bolts around the bottom edge which must be removed before taking out the injector.
The puller sets available for sale usually come with one or more different sized sockets (in case any of your vehicles have slightly non-standard sizes) and extensions as well as injector pliers which fit over the top nut on overhead style injectors to allow you to unscrew them with less risk of breaking them off.
Injectors are valves that inject fuel into the intake manifold or cylinder head of an internal combustion engine. They are usually controlled by a fuel pump, but some cars may have a separate “injection pump” for each cylinder (two in total) which is not driven by any belt. In this case, each cylinder has its own dedicated fuel supply line.
They were adapted for use on gasoline engines from hot bulb engines that used a similar method to atomize oil into combustion chambers. Hot bulb engines were used in small aircraft such as the de Havilland Gypsy Moth and early versions of the Ford Trimotor; however their power was limited by the weight of the required lubricating oil needed to prevent fouling of the hot metal parts within the engine. They were also used in large stationary power plants where they served as standby generators to provide a low speed revolving reserve during peak load periods.
When choosing an injector puller like https://frenchautospecialists.com/nissan-injector-pullers/, consider how much work you want to put into removing your injector. If you want something easy, then you can choose a simple injector puller set that should be able to remove your injector with little effort. However, if you want something more advanced, try getting an injector removal kit that comes with a variety of different tools for different situations.
