Oil fired boiler, oil pressure gauge

I have a oil pressure gauge installed permanently in the line between the pump and burner. Is that okay, or is there a chance that the gauge could fail and oil would shoot all over the place? Gauge is 0 - 200 psi, set @ 120. When the solenoid opens, the needle slams right to 120! Ever hear of a gauge failing?
Thanx!

That is fine. If the gauge does fail it will only shoot out when pressurized which is when the boiler runs. At that point you should smell oil and fix the problem. If you are nervous about it you can get a plug of the same size and only install the gauge when you want to check your pressure or adjust it.

Hope this helps a little.

Thanks spott!
Yeah, I think I'll just plug it! Don't want to take a chance on getting oil all over the basement! The boiler runs all the time pretty much! I mainly wanted to see what the experts had to say! That's a lot of flexing of the Bourdon tube!

Burner oil burner nozzle pressure gauges should be liquid filled type like one in link:

The pumps put out a slight pulsating pressure that wear out gauge mechanism causing failure, Liquid in gauges dampens that prolonging gauge life..

Nozzle pressure gauges are good way to monitoring system for status and adjusting pump pressure. Abnormal readings are reason to replaced pump. MrPopís should be replaced.

My bad! The pump is fine & the gauge is working fine! I should have said, "I have the pump SET at 120!" I was wondering if it was ok to leave a gauge connected all the time? I'm just going to plug the line & not worry about it!
Thanx!

I have my boiler serviced annually. The service tech brings his own gauge and removes it after his visit.

Would recommend leaving nozzle oil pressure gauge installed.

Gauge are good way to monitor system. Gauges are early warning of problems (needle flutters, etc.) and help trouble shoot causes of them.

Ignorance may be bliss to some, but others on cold winter, snowbound nights see assurance things are normal. When problems arise gauges help get things running faster.

A vacuum gauge on line to pump shows oil and filter status. Debris in oil is random.Good to change filter at 12" Hg

If it's one pipe oil the pump can only do 6" Hg.
