Red tube PHP10043 - under airbox - to - rear of inlet manifold
And
Yellow tube PHP10027 - under airbox - to - temp control valve

Both Brown elbows under the airbox have disintegrated

Does it matter which one of these goes to which pipe under the airbox?


Vv airbox pipes

What difference to the running of the car would these two missing vacuum tubes have made?

by the way .. the angled plastic elbows behind the inlet manifold are buggers to fit!

Vacuum pipes leaking/missing makes a big difference to how an SPI runs (fuelling). If those two have perished then it’s likely the other 2 will have as well. Should be renewed all together, plus the fuel trap, they’re a service item.

Don’t believe it makes a difference which one fits where on the underside of the air box, just need to seal well.

...and yes getting the two on to the back of the throttle body is not fun...don’t be tempted to push them on too far though as it’ll cause fuelling probs

Have also got the short fuel trap to inlet and the long fuel trap to ECU.
Was told that the fuel trap would probably be OK if just flushed out in petrol.
Also replaced the oxygen sensor in the filter housing and got a new coolant sensor for the inlet.

The two brown vacuum pipes from the inlet had disintegrated so I’ve done them first
It took so long to get the new angled end on to the inlet that I settled for that before I lost the will to live.

I’ve pushed that on the inlet pipe fully until it stopped
Are you saying it shouldn’t go all the way down both metal tube and plastic end ?

[Pops_Guild]

Sounds like you've got the other vac pipes covered too, and yes the fuel trap can be cleaned out.

 

I made mention of not pushing the two vac pipes on too far because it is possible to do. To get them on folks use all manner of 'tools' to help them, forcing them beyond where they should go is quite easy to do in the heat of the moment! If that happens the rubber of the elbow can end up blocking the pipe. That said, both of the nipples that you're pushing the pipes onto have a raised ledge which should stop this from happening, see pictures of those and how far the pipe should go...

 

…and a just to warn you if you thought getting those vac pipes were a pain in the butt to put on, you're going to love putting that sensor in the inlet manifold :)

 

...and while you're at that make sure the wire is on the TPC, like the sensor, it is also on the underside of the inlet manifold and needs to be connected (and working) for fueling.

 

Good luck!

Ah....
The pipes on the back of my inlet don’t have those coloured spacer collars so my elbow is pushed fully down.
I’ll have to make some spacers up.

[Pops_Guild]

"Spacers" sounds a much better way to describe them than "raised ledges" Good Luck

[Fastorq]

Thanks for yr advice .. could have made a mess of that simple job just by not knowing something simple .
TPC ... ?

Just found this so maybe there is a specific nipple on the filter casing for the two vacuum pipes

Sorry pic file too big ?????

[Pops_Guild]

Use MS Paint to reduce the size of the picture, takes 5 seconds to do before you post...

...TPC is this thing, it is mounted inside the underside of the inlet manifold via a big circlip.

When your fiddling at the back of the manifold it’s easy to knock off the single spade connector

use a good silicone hose instead of the factory ones
