I was thinking of the reliable ones in the Ford Traders.

at least it's not the AU one that's made of the crappiest plastic it crumbles as soon as you look at it (when it's this old)  that said, they can still be cracked on XF, probably Qld climate would be more of an issue.  XD and XE had rubber hoses that fell apart instead, so not sure what i'd prefer of the x series type. 

Those stupid vacuum lines running inside the dash, think I may have a leak under there somewhere. . Something to investigate when I get back home.   Give me the good old fashion wire control cables anytime.

@Mick.G here's a link to autobarn for the expensive one at autobarn.. (call them to be sure they have it before going down there i'd say)

I'm fairly sure there's cheaper versions with just the brake booster outlet, and one other vacuum outlet for heater etc, you could then T piece that into 2 spots if needed. 

Kilkenny Castings, make brass versions I believe?

this one is sold, 
but @SPArKy_Dave may know if anyone stocks them anymore.

I've never bought from this place, just googled
falcon XF vacuum tree ( one with the brake booster hose like yours has one bigger outlet )

Hello Gent's                   Back after a long absence from a series of unfortunate event's .All is good. Except for this PVC valve (in pic) Do not know the correct name of it Search the internet to replace it . https://ibb.co/qLS00mz4                    

I bit the bullet, ordered a PULSAR Next GEN PSR3582 XR6 turbo with the wastegate set to 11 PSI, under a grand with shipping, will need to adapt a manifold as it a T3 turbo but should be easy enough to do.   Now to collect the rest of the bits I need.   Hopefully it'll all hold together to make 350ish HP without killing the T5🤣  

I don't have any experience with Pulsar.   That said, haven't heard anything bad, and there's blokes running fast with them.
