Part Identification
 

Hi everyone, I'm new to the whole Mini scene. Just purchased an 09 JCW non running due to the old timing chain. I bought the car already torn apart to diagnose the bent valves. I have repaired the valves and I am in the process of putting it back together. Can anyone tell me what this part is? I'm thinking maybe a small fuel filter around the high pressure fuel pump...?
