I have a 2011 Bob Long G6R. I purchased the pressure test from Bob Long direct but the low pressure gauge appears to be reading way to high. I've heard people mention Ashcroft gauges but will this work with my G6R? Where can I purchase them? I'm assuming I need a pressure gauge with both high and low like the one from Bob Long? I found this but I'm not sure it's what I need:

Please advise

The gauges in the link will work.

Any gauge with 1/8 NPT threads will work.

Macroline guy doesn't have them in stock. McMaster-carr has ashcroft gauges. 3847K71 is the part number, then pick your pressure

They are large, and accurate. Only thing I disliked was the plastic housing. So keep it in a safe place, and doesn't throw it loose in a gear bag.

thanks for the input. forgive my ignorance, but don't I need a 2 gauge setup for hi/low? If I purchase an ashcroft gauge, do I just screw it into the exist Bob Long gauge housing?

Yes two gauges. The gauges simply unscrew from the housing, lefty loosy.

thank you for the clarification. I'm all set now

Do I need a 1/4 or 1/8 "pipe size". The current gauge fitting seems to be 1/2 inch. Am I misinterpreting what that means?

Im not sure you realize how big 1/2" when it comes to threading for a gauge..

My Ashcroft gauges arrive from McMaster today. They work great! Thanks to everyone for all the advice. My original Bob Long gauge was off by ~15 PSI on the low pressure side
