oil return silicone pipe

[renault5gtboi]

what size silicone hose do i need on my phase 2 c1j engine from my sump to the oil return pipe that connects to the metal pipe going back up to the turbo? as i have bought one from cgb and this was a genuine one but it seems to be leeking at the sump end , could my sump be off a phase 1??? could it be a 20mm reducer to a 16mm?? any info will be appreciated :) becouse waisting this mobil 1 oil is so expensive lol

think the phase 2 pipes are the same top and bottom but phase one sump is smaller so im guessing you have a phase 1 sump,therefore need correct return hose.

cant tell you what the difference is in size of pipes though.
