Fx said they know their old gauges on the impact isn't accurate thats why they upgrading it to the newer one this year. If they are aware it's poopty, do you think they will swap old gauges for new one if we request it? Or at least give a discount if we sent in the old gauge? Both bottle gauge and reg gauge doesn't match when off the reg pressure. One would read higher than the other. Also they don't match what my big CF tank gauge says. I will be upgrading to the newer gauge when they come out. Just asking if I have to pay full price for 2 new gauges or not.
