There is no need for an electrical system to operate the gauge, so it can be used on any street or race vehicle.

1/8" nylon line, T-Fitting, vacuum fittings, compression fittings, bulb and socket assembly, red and green bulb covers, mounting hardware, and detailed installation instructions are all included in the gauge kit.

Even in the harshest conditions, mechanical movements provide precision and durability.

Questions & Answers

What gauge size is this, 21/16"?

2 1/16

Is the backlight a different color?

The typical whiteish yellow glow of an incandescent bulb is present. If my memory serves me correctly, it comes with two bulb covers. Red and green are two complementary colors.

What size hose does this gauge come with?

The hardware included with the gauge is not of the same high quality as the gauge itself. Wrxtra's boost gauge installation kit is something I highly recommend. com. For a very low price (less than $20 shipped), it's an incredible well-made kit to install this gauge with. Because of the poorly made plastic T fitting, I had a very bad boost leak after installing the gauge with the kit provided. Then I came across this kit, which hasn't leaked in over a year.

Selected User Reviews For Auto Meter 4301 Ultra-Lite Mechanical Boost/Vacuum Gauge

From the factory, the calibration was incorrect

3/5

Before shipping, they should double-check these items. The gauge reads - when the car is turned off. 2mmHg. br>br>While this does not appear to affect the accuracy of the boost reading because it matches what my Profec says, it is still annoying. For 80 dollars, I'm hoping for something that isn't broken when it arrives. br>br>I purchased this gauge, as well as an AFR and a water temperature gauge. The boost gauge is incorrectly calibrated, and the water temp gauge's housing is damaged (flat spot on the ring). which you can't repair without destroying the housing and voiding the warranty - The AFR gauge's instructions are among the most difficult to understand I've ever seen. br>br>Please keep in mind that I'm an electrical engineer with over 20 years of experience working on automobiles. I've seen some truly awful instructions in my time (see Any Engineering Manual Ever), but these were the worst. I wish I had purchased a different model or from a different manufacturer. br>br>.

This is not the gauge to use if you need precision

4/5

My boost/vacuum gauge is not properly calibrated, as stated in other reviews, and I will have to send it in for repair. Installing it was a breeze. In a Dodge Challenger 5, I put it in. A Whipple supercharger boosts the engine to 7 liters.

This is an excellent purchase

5/5

The boost gauge is extremely responsive. The other gauge I had was a little slower and less accurate than this one. Because of the White colors, this gauge is much more accurate and visible.

Much better than the electronic propsport gauges I had ordered previously

4/5

Much better than the electronic propsport gauges I had ordered previously. In my turbo 3sgte mr2, I installed this gauge. I did have to use some adapter hoses to connect to the vacuum line I wanted to use, and the included air tube tends to kink on sharper bends. The material is quite stiff.
