Auto Meter 4305 Ultra-Lite Mechanical Boost Gauge, Regular, 2.3125 in.

Came with everything it's supposed to, great gauge. Only suggestion would be, since this is a boost only gauge it's likely being used in diesel applications and should come with a no-buzz fitting as an option. Gauge makes quite the noise and if you prefer a quiet cabin, you'll want a no-buzz fitting.

Good

Wish it was brighter.

Awesome gauge not jerky very smooth operation !

Great price, fast shipping

Gauges are very good, and accurate. But don’t like the fact that they fog up first 20 minutes or so of driving.

I bought 4 of these gauges. None of them came with the 1/4 npt adapter. The description said it did.I called Autometer Customer Service... and got a smart aleck rep who seemed more impressed with making gauges fit for a dragster than for a big truck. If you are installing in a big truck then you'll be needing the 1/4 npt adapter. I go through alot of these gauges... and can say for sure that the Sunpro cp7027 comes complete with the 1/4 npt adapter. Amazon sells it for half the price this one sells for. I figure I should have all the parts... if I am going to spend twice as much. Not having a $2 adapter... is not so terrible. Saying it has it and not including it... costs me time... and is a big interruption. I was also missing other parts, on some of the guages. I won't touch Autometer once these 4 are gone, do to their poor Customer Service Reps.

Defective out of the box, it was reads 5psi not hooked up to anything, i ordered a replacement and now i halfto go to the ups store to ship this defective one back. Very unhappy with the product, il halfto wait a almost 2 weeks to get the replacement.
