The EVAP system has something to so with allowing fuel vapours to enter the intake manifold, but Im not really up to speed with it. I think all H22's should have the EVAP purge valve, yours is deffo not in the normal attached location.

If you have a look at the 4th or 5th gen service manuals it shows the vacuum hose configuration diagrams.

Is that manual on here for 4g

Yup in the Wiki-Lude under Honda Service Manuals. The 4th gen one is a bit crap as the H22 bits are spread over some supplements. Here is the 4G H22 bit http://media.honda.co.uk/car/owner/medi ... 2ss020.pdf

Definitely been tinkered with, that should not be there. Can you get some better pics of where the vac lines go. Also is that a plug beneath it?
