2ZR Vacuum Hose (TRD Airbox install)

[SH]

Fitted a TRD airbox and K&N filter to my Cup 250.

i can’t remember pulling a hose off the T-Piece (in red circle)... nor can I find a corresponding hose ending to plug into it.

Is it left ‘open’? - I can hear air being pulled through it.

*Think* I have my answer!

DeRoure list a 'blanking plug, Vacuum hose T piece' at 14 on this diagram.  I must have knocked it off when faffing about.

 

 

 

 

Now plugged!

Why didn't you replace those three hoses, t-fitting and screw plug with one longer hose? That way you would have only two locations for potential leaks instead of the six that you have right now.

It appears that the short hose is bonded to the one-way valve - I'm not ripping it off.

Toyota / Lotus seem confident that the draw in the vacuum system isn't going to trouble the push-in joints / blanking plugs, so I'm not going to lose any sleep about it. 

The only changes that I might make for neatness would be to replace the T-piece on the right with a 2-piece connector, and replace the bolt / hose on the left with a proper blanking cap.

i completly removed all hoses and sealed the only opening in the intake manifold right next to bolt no 6
