This tube, which I hope is visible in the photos, runs from the top of the air filter housing, the MAF sensor and looks as though it should connect somewhere with the inlet manifold but I cannot find where it should attach :bang:
Any ideas?

I also have a problem when the van is parked overnight whereby the fuel seems to siphon back to the fuel tank which suggests to me that air is getting in to the fuel system somewhere at the engine end. It means that it takes ages turning the engine over to get the engine started in the morning but she fires up instantly anytime after that.

Any suggestions welcomed.

Thanks

Looks like a vacuum line,

Not sure what the device is with the yellow electrical plug..?

But the other end Is probably on a stub under the airbox,
500 petrol cars are always having these sheared off
