What is the secondary filter made of?
The secondary filter is made of a paper element. This filter controls the size of the particles allowed to pass into the fuel injectors.
Why do diesels have 2 fuel filters?
The answer is quite simple. Many machines have small electric inline fuel pumps to raise the fuel to the engine and help provide a chance that a diesel may self prime if run out of fuel. The first filter protects this electric pump, the 2nd protects the engines fuel injectors if that pump happens to fall appart.
