S1 Water trap hose query.

[Gazlar53]

Hi,

Hope you're all well. 

Can anyone tell me what diameter hose I need for this thing, see red arrow on picture below (which I think is a water trap, but I'm probably wrong?).

I assume that if I just order some vacuum hose that will be fit for purpose?

Many thanks,

I think the trap is for fuel vapour, but either way it traps liquid of some sort to stop it damaging the sensor in the ECU.

Just is a standard vacuum hose.  A pretty skinny one.  Smaller than 3/16" ID.  1/8" or 3mm perhaps, see what you think if you have yours off already.  Get a good quality one, you don't want it collapsing.
