1/8 compression fitting for boost gauge...

[Quickstop [UK]]

I deserve ridicule for this but need to know...

I have an autometer Phantom gauge that I am trying to install, but have not got any instructions and cannot get them off the site.

I have got the 3/8 fittings into the main part of the engine as per the tips page...

I have 2 alternatives:

1) A 1/8 NPT with a 1/4" barb internal diameter hose to the gauge. i have just thought that perhaps, the volume of that hose is too much...arse.

2) The gauge came with a type of compression fitting. i have never seen one like that before.

I tried ordering the fitting on

Can anyone explain what diameter hose I should order and what fittings i need and where to get them and how to fit them?

Sorry for being such a helpless individual....

Why is it so hard to find the right bits for this car? :rant:

And thanks for any help....

the back of the gauge has a 1/8" npt male.. You use their compression fitting that goes from the male to the plastic vacuum line.. then you can either "T" into the vacuum lines or install something like our brake booster hose

which comes with a port specifically for the boost gauge, and the compression fitting to install the plastic line. Benefits of this is that it wont interupt the signal to the map sensor or fuel pressure ragulator.

That is how I have planned on doing it. I have a similar block where yours is (3/8" into engine with the hose going off to the brake drum).

Where the silver braided hose ends on the brake drum there is a silver fitting. Mine is plastic (stock). Where can I get one like yours?

Also, where can I get a compression fitting like the one that goes on the back of the gauge?

I have ordered a 1/8 male - male NPT for the port into the brake booster hose...

That is a nice set up : )

I personally dislike the way the compression fitting / plastic hose off the brake booster looks...so I went a different route.

I put a barb fitting on the boost gauge, and got a triple vacuum port that fit into the rear of the upper intake where we usually only have a single port. This also allowed me to get rid of the vacuum port on the front of the upper intake.

Unfortunately, i have no clue what i got this port from. I noticed it at the junkyard one day and took it....and sure enough it fit. I wish i'd gotten a bunch of them or at least taken note as to what the hell i took it off of.

I have managed to find some of those compression fittings (I hope). They ar 1/8 OD right?

I have spent a fortune today on these tiny little pieces to make my Boost gauge work!

My method cost me $4.50 at lowes for a barb fitting and adapter...and I had silicone tubing laying around....and the junkyard didn't charge me for the vacuum port :tup:

That is another reason I will prob end up in the US. i spent around $80 today on various permutations....
