Gents, just wondering what the hell this thing is. I had a mate help me install an aftermarket boost gauge, whilst I was doing electronics, he t'd into a vacuum line and it was working great. Not long after, noticed my vacuum sits at about -6 now and found the leak - stock hose split on either side of the T piece.

Replaced stock split hose that runs to the manifold with the blue silicone tubing which has been great, the other side that is split is connected to something in the upper left corner of the engine bay I can't quite see and was wondering if I could also replace this hose with my silicone tubing. The clear tubing runs to the gauge.

If your talking about the black rubber hose on the other side of the 'T', it is for your stock boost gauge. The one on the dash. You can replace the tubing for that as well but probably need to get the back of the dash.

Yeah, that think vacuum hose just behind that fluid tank, that runs underneath and up into whatever that oval-like thing is with SAE written on it. Just wanted to know if I could pull that unit out and replace the stock hose with my silicone and replace that unit, just wasn't sure what it was

Silicon hose won't go to the dash. It'll run from the manifold to the sensor shown.

Stock boost sensor, got it. I'll try run a new hose to this, not real fussed as the stock gauge was rubbish anyway but would be nice to still have it functional (somewhat)

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
