FX Leaking from back reg gauge

[PCPGUY]

Just installed power block and 750 plenum on my gen1 impact. Everything went well except….when screw bottle in it starts leaking at back reg gauge. Anyone run into this and know what I need to do???? Thanks

Sounds as if the O-ring for the pressure gauge may have gone bad. Looking at the schematic on the FX Support page I see the part as B-34, #19723. If you are so inclined, I would replace the plastic gasket with an X-ring - 3.63x2.62 NBR70 #19762 is what lists for the MKII.

There is no O ring if I’m not mistaken

I don’t see an O ring or how the gauge is possibly connecting there

Here is the FX Schematic for the Impact MKI: https://fxairguns.com/wp-content/uploads/2021/04/Impact-MkI-1.pdf. If you look at section B, parts 35 & 34, you will note they are listed as a pressure gauge and pressure gauge washer 'thin'. Since you have stated the air leak you are experiencing is from where the pressure gauge connects to the rifle, I suspect you have lost the thin washer and need to replace it.

Thank you for that! Just got off the phone and ordered a few X rings
