new owner of a 2002 Td42 coil cab probably a stupid and obvious question but I have been looking through my manual but I can’t find this catch can looking thing in the book as seen in the photos. Is it a aftermarket catch can? If anyone knows it would be greatly appreciated
It’s a vacuum canister. Don’t touch!Quote:

As above. They are vacuum tanks. They hold vacuum in them for your brakes and clutch as the vacuum pump alone is not enough. So vacuum is stored in them pretty much.
For some reason they were on pre 2003 models only. Must of changed something in series 3.Quote:

Yeah not sure why. They might have changed the style of the vacuum pump or something. Or just worked out the tanks wern't really needed...Quote:

Not sure what motors everyone’s trucks above are running and or previous to conversions etc... I can only nuffy assume that from quite a few owned 1999-2002 4.2 diesels always same factory twin cannisters must’ve required extra vacuum storage found by Mr Nissan too late? Petrols and quite possibly 3.0L diesels possibly had enough suck for one cannister only maybe to meet ADR’s?

Still sad though because successive pumps when car idle it still goes stiffer. I know our clutches are huge and I assume the hydraulic isnt enough but surely theres got to be a better way? lol
Same , my old GU3 ZD has one and my clutch was the same and was worse after installing a single mass clutch. I even replaced all the hydraulics with little improvementsQuote:

Why is that sad? There's no need for successive pumps of the clutch or brake pedal unless your bleeding the system. Its normal really, diesels just dont produce the amount of vacuum like a petty motor can. The system works, and works as it was designed too.Quote:

Offroading, rock climbing, offroading. Clutch in and out. Not a deal breaker but nevertheless.Quote:

@mudski good mate! Are you sure that a GQ alternator with rear vac pump can bolt onto a GU like our stocky wagon?

Do have a GQ custom 170amp on my 6.5NA ute up top with vac needed and was hoping to swap it across oneday.
Chev diesel will get a birfday eventually of serious alt and elecy vacuum.

Now you got me thinking MB. It was a while back I did see a GU with a GQ alternator on it at JPC's workshop, was a blacktop too. At worst you'd have to use different alternator mounts if needed or are different.Quote:

Yeah possibly. I got two. More vacuum to hold the better. But there’s clearly two in that pic.Quote:
