    What diameter of hose can i use for the actuator to N75 connection?

    I'm just giving all the hoses a once over to try and hunt any splits.

    Think 6mm should be good, I took out all the N249 stuff earlier and removing all the PVC pipework because I still havnt fitted my oil catch can! I was just getting to the N75 bits as it got dark so gave up but should be able to confirm tomorrow if the weathers alright!

    i fitted 3mm when doing the n249 bypass.
    ive got a few metres of 5mm and 8mm to do a few other bits

    id like to get rid of the SAI and PVC pipework, but dont have a clue where to start (and ive read the guides already lol)

    Yeah 3 or 4mm is fine for the N249 bypass (inlet manifold to the DV) but cant see that being the right size for the the N75 to the actuator think it needs to be just a bit bigger than that!?

    Correct Dave. I wanted to replace the hose that goes from the actuator to the N75 valve. I think the hose is ok but thought i'd change it while I was there.
