Bored at work. Sorry for all the questions ![Tongue Tongue](https://www.306oc.co.uk/forum/images/smilies/tongue.png)
What does this do? Two of the lines goes to the filter, and the other two to the pump.
The lines are very small. And can't say I have noticed it on any of the engine bay pictures I have seen. Why does the diesel have to go through this? Why not just connect directly between the filter and pump?
