Marshall Instruments LBB00100 Fuel Pressure Gauge Black

Good quality gauge. No issues or leaks. One of the best for the price.

Does what it's supposed to. Setup in a high pressure Holley sniper 2 setup

The gauge was placed inline to the fuel line. The oil filled display provides for an excellent display without vibration. It reads the fuel pressure correctly. It's presence tells me exactly what I need to know when doing trouble shooting or just making sure the fuel pump is working correctly

I used this gauge as part of the conversion to a Holley Sniper EFI system on my 67 Mustang with an Inline 6 so I could monitor fuel pressure coming into the Sniper unit. The gauge is everything I expected. It was easy to install, easy to read, and is accurate. It seems to be quality construction well worth the cost and then some. I have only been running it for a couple of weeks now but so far so good. I would recommend it for this type of application for sure.

Second one I’ve bought definitely recommend

Installed in rear of SPEC Miata (for racing). Provides nice read-out when adjusting fuel pressure on the rear mounted fuel regulator.

Todavia no se ha instalado porque estoy esperando otras piezas ,tiene buena aspecto

Ive had this gauge since February of 2017. And i think it stopped reading properly about 6 months to a year ago (currently aug 2019). My fuel pump hasnt been workin properly for like a month now, its been whining and my digital fuel pressure gauge in the cabin on my 1 off quad gauge pod has been fluctuating from 55 psi to 85-90 psi, never really constant. Before the pump went bad it would maintain pretty much a steady pressure. But while my digital gauge is fluctuating all over the place, my analog marshall gauge Under The HOOD seems to be reading a steady pressure and i know thas not right cuz it misfires a little at idle and the pump is whining pretty loud and the fluctuating digital gauge reading of course. And the aftermarket PLX fuel pressure sensor is right next to the marshall fuel gauge as u can see in my pix. Now however the author of this listing has not mentioned anything about warranty on this listing so ill prolly jus get another one or something different unless the seller is willing to do an exchange. One other thing, you guys might be wondering why I capitalized "Under The HOOD" in my last paragraph. Well thats because this gauge belongs under the hood in front of the firewall not in the cabin. A couple ppl have posted that they have it in the cabin to monitor nitrous pressures or oil pressures or fuel pressures. You should not be running nitrous or fuel or oil lines into the cabin or past the firewall at all for that matter. The proper way to do it would be to get a sensor and then run wiring into the cabin. People that have these gauges in your cockpits please be extremely careful and triple check your lines and clamps and what not or do it the proper way and get a sensor and run wiring into the cabin.

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.
