Recently fitted some gauges including oil pressure to a MY02 WRX. I fitted the oil pressure sender under the alternator (with a relocation pipe from LMA). Problem is, whilst I was doing this I managed to disturb and pull off several vacum hoses in that area (to the left of the alternator). It was straight forward where a few of these went but I have one that I am unsure of and a 'T' piece with no pipe on. See photos below where hopfully this is simpler.....sorry the images are large - not sure how to resize.

Picture 1.


Picture 2 - Blue 'T' piece.



Picture 3 - Loose Pipe.


Should these both be vented to atmosphere or some how connected together (they are both in a similar location) - remember the pipe diameters are different though. The car has began to be a little lumpy on tickover (not excessive but not as smooth as usual) but performs OK otherwise.

 

i think you need to resize you pics mate
