Rated 2 out of 5 by from 1 1/2 inch oil pressure gauge Custom mounted the gauge on my motorcycle. It worked fine for a 1000 miles then the needle would not return to 0 after the engine shut down but rather stayed at 45 psi. It now pegs out at 100 psi with the engine running. I might buy another one but if it fails or does the same thing, it will be the last.

Is this gauge safe to be mounted under the hood to the regulator? Just wondering about heat and whatever it's filled with. Thanks,

Asked by: PeterKChicago
Thank you for contacting us. I would say it’s built to be direct engine mounted in the engine compartment, as opposed to regulator. Regulator would be more specific to a 15 psi fuel pressure. This is 100 psi so it can be used for oil pressure, fuel injection (fuel rail), etc.

Asked by: Dan D.
Hi Dan, This 2174 does not come with a bracket. It is designed to be screwed directly into the pressure port under hood. Thanks, Jim
