Good work - 3/4 is about right for normal running. I gave my modded APC box a run this evening ... Niiiiiiice :P >> I had the hose that runs across the bulkhead connected to the valve and >> the hose that goes under the dash behind the cabin filter connected to >> the plain barb conenctor. Is that correct? > > That's correct. Is that (the first one) the one from the intake manifold through the valve? Does that T-connector on the intake manifold also pressure the APC gauge? I'm looking into hooking up a graduated vac/boost gauge - does anyone have source for a suitable gauge? I like the VDO white faced gauges, but cannot find a retailer. >> Just need to work out if it is the cannister, the valve, or my >> connecting of the hoses that was dud. > > Unless the bottle's split, it's the valve. In situ, if you can hook up a pump (say a car tyre pump with a gauge) to the cannister inlet and block the outlet, you should be able to tell if the cannister is leaking. What about removing the cannister, blocking the outlet, pressurising it and immersing it in a sinkful of water? You'll see where the leak is, if there is one, and maybe be able to seal it with a puncture repair kit - would that take the pressure? Good luck - it looks like you're onto a winner here.
