I have an issue filling the Marauder I purchased from the classifieds. The regulator that the owner had installed is tied to the onboard pressure gauge, so I cannot go by it for refilling the gun from a 88 cu ft Air Hog set. Unfortunately due to the Air Hog only having one gauge on the tank, there is no way to fill the Marauder safely without another gauge. Can't afford a new tank valve with 2 gauges right now. I am rather skeptical about the Air Venturi Inline Air Pressure Gauge, 0 to 4500 psi just from the looks of it. But I do realize it is a picture. Has anyone used one or currently using one, had one in their hand to examine? If so; How well is it built? Is the gauge adaquite for a relatively precise fill? Might it be possible the gauge is removable so a better glycerin filled quality gauge could be installed?
I cannot figure a way to post a link to the inline gauge without posting a from a website selling them, Hopefully it is not against the rules, none I have read at least.. Amazon is the most generic site I can post a link from that I can find https://www.amazon.com/Air-Venturi-Inline-Pressure-Gauge/dp/B005EXDCYE

This does not appear to be the same gauge pictured on current ads, but my old eyes are not the best around either.
Also, I have searched the web and spoke with several "Counter persons" about the parts needed to build one. A "tee", male foster fill, female foster fill (QD) and a 6000psi glycerin filled quality gauge would work. Problem is, seems no place I have looked or spoken with have all the parts with matching threads.I do have several query's in progress that will not be answered till Tuesday at the earliest.
Your feedback, ideas or thoughts will be more than welcome. This is my 1st venture into PCPs and I thought I had all the bases covered until everything arrived so I could put all the reading I had done into actions. Talk about a downer.
Thanks
