Marshall Instruments LBB00100 Fuel Pressure Gauge Black

Well built and accurate gauge. Has been living under my greasy old ford for 4 months through gravel roads, mud, and snow. No leaks and still easy to read. I imagine it would hold up to most situations considering what I put it through

WAY cheaper than other options and actually looks way better too. Marshall has been around long enough that I trust their products to deliver accurate readings. Fit my fuel pressure regulator perfectly, just make sure to use some PTFE tape on the threads as NPT threads are not self sealing.Liquid filling is very thick and doesn't vibrate around at all, looks extremely professional and high quality. Matches my aeromotive regulator too!

Easy install and looks great.

i have this gage installed and it's good out of the box. no leaks and needle is steady, no pulsing etc. I have not run it very long so i can't give you any input on longevity etc. It is finished well so if looks are important the gage finish and fit are just fine. For the money it's a good piece. I will use this for initial setting and data until i have everything dialed on the fuel injection. After that my ECU will give me what i need.

The media could not be loaded. Marshall is a great product with a great backing of the name. Been in the gauge business for ever and a brand you can trust. No leaks gauge is accurate and the coating has held up and is easy to read.I’ve had the OG car guys ask me about it.

Very nice looking fuel pressure gauge but if it’s tilted at 45 degrees, you can see the fluid doesn’t fill up the gauge unless it’s up right. Not a big deal but it just looks funny with the fluid going across the logo

Even after the motor gets up to temp and the engine bay is hot the needle is steady and fairly accurate. I already had an aftermarket fuel rail and my regulator housing had a port for a gauge so this thing worked perfect for my purpose. Great product great price

I replaced an aeromotive gauge with this and it works great in my E85 tuned rb20det

Just keep it hooked up in the engine bay along with my adjustable Fuel pressure regulator and it hasn't failed in over a year (probably 2 now)and no leaks. High quality item for sure. Would buy again.

Lecture très claire et précise. C'est tout ce que je veux savoir!

Accurate, used for oil pressure on a motorcycle.
