Problem Resolved...Anyone fimilar with the Air Venturi Inline Air Pressure Gauge

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

Someone from another forum mentioned getting with Tim at Mac 1 Airguns. So I sent him a PM yesterday, figuring it would be Tuesday before he read it. Described what I had pictured in my mind. Got a PM back with his number and gave him a call. Not 15 minutes later, everything is ready to roll. Female Foster on one end, male on the other with a 5000 psi glycerin filled gauge on top. All parts rated at 5000 psi. He could have saved a few bucks using cheaper materials, but as he put it, this is the way he would build it for himself. Can't ask for more. Sometimes you just need a problem solver, think I have found one now.

I have know Tim, for many, many years, although I have not seen him in a long while.

I can tell you if you want something done right and not a Mickey Mouse job... Tim is your man.

You could also build it yourself with parts from north shore compressor. 
As to the item in question, I have no experience with them. I know those little gauges can be off by quite bit. So, I'd look at getting some better quality ones. I saw a post by Ernest Rowe where he replaced the stock gauges on his Impact. You might shoot him a PM and ask where he got them from, if you do decide to buy that setup. They were slightly larger but, from what I understand, much more accurate. 
 
The Air Venturi may be good, but with my old eyes, that gauge is way to small also I read. The one I ordered, only paid for the parts and postage has a larger excellent gauge, liquid filled, with much more detailed face, everything rated at 5000 psi. It should last well longer than I will be around...lol The guy I spoke with briefly end of last week at North Shore emailed today, said he was having problems finding a T that would work. Told him thanks and I had located all the matching parts.
I do appreciate the feedback
