Who would have thought a new guage would start sucking air? Does WVO contaminate the innards if it contacts inside the guage?
Bypassed for now and no more bubbles; no, it wasn't the line and/or the connections.
Any brand guage better than others? This was a cheapo JC Whitney job, if I recall.
Also gave me a chance to check all of the fittings to the pump.
This is turning out to be a local crowd favorite!
FYI for all;
Thanks,

I had a leaky vacuum gauge causing me problems.
I put a different one on and everything worked fine.
Meanwhile, I opened up the leaking one and found a bad solder seal on the inside.
I fixed it with a soldering iron and solder.
