How to remove this rounded screw

[MisterGTR]

I shouldn't have thought it would make much difference to flow, considering the area of that pipe, is not dissimilar to the dimensions of the hose it goes down to, that little bit in the middle is probably insignificant. Peugeot probably had a rough idea when they were designing it

Either way, glad its sorted

That's very true.

Thanks

Need to figure out if condenser will come out without bumper coming off tomorrow. More fun and games for sure
