The 1-1/2" dial is easy to read, and the 1/8" NPT lower mount makes installation simple. It’s perfect for anyone needing a reliable, low-pressure gauge for automotive or small engine use.

works good

Quality gauge, fit & finish is good, works/reads accurate. No leaks

This appears to be a very nicely constructed gauge. However, in all fairness, I have not installed or tested this yet.

Awesome product for the dollar. I will let you know 6 months from now

nice little gauge, liquid filled

I noticed the pressure would decrease the hotter the engine got and gauge of course. After googling it it turns out oil filled gauges will lose 1psi for every 30deg increase in temp. Not really great when it's on a hard line connected to the carb which can get upwards of 150F. It would start out at 6psi and drop to 3. I drained the oil and haven't tested it again, but i have no reason to doubt the internets. Update: Save your money and buy a better gauge. This worked for two starts now it starts at zero even when cold and slowly goes up. Cheap trash like 99% of the gauges on here. If you can find a fuel pressure gauge made in the USA buy that!
