Reply To: FX Bobcat MK2 air tube leaking through end cap
Not sure what you meant by this:
“I believe I canned part of the brass monometer through thru hole”
However, the small hole in the housing the manometer threads into is used for bleeding the air before removing the gauge itself.
If you start to unscrew the gauge, you should start to hear hissing. Let it bleed all the way to empty, then you should be able to remove the gauge all the way.
Examine the threads, both the male and female. Clean them, check for contaminants, and make sure there is nothing blocking the male thread from going all the way down to the female thread well.
There appears to be no o-ring or sealant involved in this fitting assembly. So screw the gauge back in, tighten using 11mm wrench, and be careful not to strip the threads.
If this does not work, apply teflon thread sealant tape to the male part, 6 layers should be sufficient.
