Question: what is this? Its leaking fuel. Part no? Its under/behind the intake Y, above the thermo housing.

EDIT: Its part no. 1574E8. It seems I need to change the whole piping :/








Hi joopajaa,
well done is noticing the leak, that brittle pipe/connection gets very brittle over time and leaks fuel intially very slowly, but then gets worse! Your best bet is replacing the injector pipes as well. I have mine bought, but no leak as yet, but I'm checking just in case. E3steve mentioned it on the forum if I remember well this issue along with the vacuum pipes for the manifold that run across the top of the engine as well.

Regards
Dave

Comment on this after the belt change: My front intake was quite loose. I had to tighten 2 lugs near the belt side. Not sure yet if this has any affect but I think there was some leaking going on because of this. So check your intakes!

Also it seems my fix with sikaflex-type adhesive + split silicon hose over the piping near Y-part has stopped the leak.

Any ideas on this? I did not find visually any leaks from intake, did not had a change to try with compressed air yet. I still have the off-balance with intake air readings.
