    guage

    The gauge should come with a vaccuum line. Not sure what you mean. The line should run from the gauge to either the IC blockoff (if you have a aftermarket IC. If not, it should go to the intake manifold nipple. There are small ones and big ones. Tap into one of the small ones and ziptie a line to the nipple and it will give you a boost reading.

    I drilled and tapped the IC blockoff under the intake manifold with 1/8" pipe thread and put the fitting there. I use a 1/8" pipe plug when it's not in use.

    Depends on the gauge. Most of the time you have to buy your gauge then buy the capilarry tube kit and it comes with all the ferrules/fittings you need.

    This is the kit I bought from Jegs: http://www.jegs.com/i/JEGS/555/41050/10002/-1

    The gauge:

    Still work. That guage is really meant for a 1/8" port on a fuel feed line on a carb. But with the capilarry tube kit I got it will hook right to the 1/8" NPT fitting on the back of the gauge. Then tap it to the T fitting I got for my IC block -off. Done deal.

    That Jegs Gauge is actually made by Marshall Instruments. Actually the same gauge that is used on the Rude RRFPR. Anyway the gauge is full stainless bezel/case. Its sealed to hold in the fluid. So I consider the fact that it will be sealed very well to the elements. (not trying to preach them up, we use the gauges alot at work and they hold up well to the elements) Its suited to what I want. A small, mechanical gauge thats cheap to replace if need be. I dont want to hack up my mirrors. So im fabbing a small aluminum bracket to put the gauge in the glove box. Will work for what I need.
