What size of "T" would I be needing? I want to try and source one, but these are things that the local stores don't tend to have around. Anyone know an online place I can get one?

Amazingly enough my gauges came this morning

Considering I requested they be sent by snail mail I thought I'd be waiting quite a while longer than you guys, but they're here!
They look like a million bucks. If I get a chance to mount it today or tomorrow, I'll snap some pics of it mounted.
So I'm going to have it to show off at this weekend's Rx7 Meet in Ottawa, good job billy.
I can't decide whether I want to put that little filter thingie (shown to the right of the gauge in the first pic on page 5) before or after the quick disconnect stuff. If I put it before, it'll stop crap from getting in the quick disconnect pieces, but if I put it after (attached to the gauge) I'll be able to clean it.
And I think that the filter might provide a bit of resistance, since it's hard to blow through... so I think I'm going to try it quickly with and without it to see if there's any difference.
Unless I'm mis-interpreting its purpose and its not a filter at all, but one of those things where you have the gas pressure on one side and you put a liquid that won't harm your gauge on the other.....
billy can you clarify?

Following is a gauge I purchased from McMaster-Carr in year 2000 for $37.81 including ship. Do a search for McMaster-Carr
part # 4026K27, gauge grade A, 2 1/2 inch dial diameter, 1/4 inch NPT Male bottom, 0-5 psi, accuracy +/- 1.5% of full range meaning .015 x 5 psi = +/- .075 psi.
I did not read all the posts but the snubber some of you have mentioned is to eliminate liquid shock to the gauge.
Do NOT install this gauge inside the car. The deal that makes the gauge function is a .005 thick brass diafram. Even if you plumb with a so called steel line the friken diafram could bust & make you wet with gas & with one little ol spark. To my knowledge most of these price range gauges have similar diaframs.

Yea McEverything was the first place I looked. That gauge is no where near as accurate as a 1% 10PSI gauge though and hardly any cost savings yp show for it.

Is the snubber really necessary? Most of the guages on the McDaniel Controls inc site are rated for 130% load safely, and with a 6psi fuel pump and a 1-4psi FPR I don't think I'll be hitting pressure spikes of 13+psi anytime soon.
Just wondering. It's a good precaution and Paul Yaw used them on his 0-5psi gauges because pressure spikes are often seen in the 7psi range, but on this one, it just adds to the whole unweildly-ness of the assembly.
Not that I'd tend to complain about a part which is meant to protect my investment.
I got my "T" and will be installing it sometime before the meet tomorrow

I would say the cheaper the regulator the more you need the snubber. I through it in just to be on the safe side.
