2ZR Vacuum Hose (TRD Airbox install)


Recommended Posts

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.

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

*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.

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.

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.
