Where does this go?

Having just replaced the water pump on my 2001 3200, which took rather longer than expected, largely down to not being rushed rather than mechanical ineptitude! I am approaching completion, I must say how helpful the threads on cambelt and water pump removal are. But I am left with a dilemma.

The secondary air system on the later models has two valves at the top front of the engine - these are connected by an air tube into a 'Y' connection piece (part number 28 on the diagram and shown as the white bit of plastic in the photo)

Normally I carefully mark everything and colour code with paint, this I clearly forgot! where does it go - there should be a bit of flexible rubber pipe floating around somewhere BUT WHERE IS IT? its not the one on top of the TB, that is just a vent.
I don't even have a spare bit of pipe so I assume that one end is still connected to whatever it should be. The euro spares diagrams list the two pipes to the Y piece and then show in dotted the pipe I am missing

Any suggestions greatly appreciated.

From memory, I think you will find that there is a vacuum hose that runs down by the LHS (facing front of car) air filter housing and or rad, that then plus into the single end of the Y piece where both hoses go to the EVAP valves.

Ha ha Found it!
You are right, when I put the fan housing back, I had caught the pipe and trapped it out of site.
All connected now, just spark plugs, water pipes and all the associated pipes, wires and other bits to connect up.

That job looks too complex for me, big round of applause for getting it done.

To be fair it is not difficult, very fiddly and time consuming, frustrating when Maserati insistence on using Allen head bolts results in one rounding off because it is tight. Eurospares listed one bolt for the Cambelt tensioner at £6.71 - cost me 20pence from a local parts shop!
The rest is confidence and understanding how an engine works, taking care when lining up timing marks to ensure it all goes back the same way!

The car is in a garage, I have a good selection of tools and was in no rush, it all helps.

I'd just disconnect the fan motor altogether It's not necessary.. It was there to get though the Euro 3 emissions all those years ago to heat the cats up quicker on cold starts

If your off for an MOT emission test, the engine will be warmed up already!
