Frequently Asked Questions - Fuel Systems
 
Question: Why do I need post and pre pump fuel filters?

Answer: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.
