Fuel Filter Bullet Type, Pre Injection Pump
A pre injection pump fuel filter with -8 JIC ends.
We always use a post pump filter as well as a pre pump filter. The pre pump filter removes particles from the tank, whereas the post pump filter prevents particles passing to the injectors and fuel regulator. The reason it is used is that the fuel pump uses fuel to lubricate itself and if the pump ever begins to fail, it begins to deposit particles from the failing pump into the fuel system.
