CARBO Instruments 1-1/2" Fuel Pressure Gauge, Stainless Steel Case 304, Chrome Plated Brass Connection, Glycerin Filled, 0-15 Psi, Accuracy 3-2-3%, Lower Mount 1/8" NPT

I needed a quality, but reasonably priced, low pressure guage. Tuning my BMW 435i for max power is simple, tuning it to be daily drivable was much more difficult. Max power is just uploading the prepared tune. However in my daily commute that proved to be difficult to drive hard on gas. The stock turbo can only push around 20 psi max. Most boost gauges read both vacuum and up to 30 psi on one tiny guage. This was great for seeing what boost was doing and when. Now I have a "race" tune and a "daily driver" tune. As for the guage itself, it's well built, glycerine filled for smooth but quick action. If there is one draw back, it's the hose fitting is 1/8 npt which I had to order. Not a problem, just needed to read the discussion. Lol

Needed to monitor fuel pressure of lift pump on a vehicle to ensure a oil pressure switch was functioning. Works well and I may leave it on the vehicle so I can check it whenever I would like. Clear easy to read dial and comes with some hoses and clamps to install it in line.

Gauge was as described, accurate, and well made from what I can tell so far...Time will tell! Overall very pleased with this purchase.

I used this gauge to set the pressure on my shop space heater, worked great! I do not know just how precise the accuracy is, however, it was close enough to set-up my heater after a rebuild of the pump. I was warm all winter.

Works great and it seems to be accurate and repeatable

Bought a fuel rail from another vendor (black hoses and fittings). It had a white faced gauge with too large of a scale. Purchased this as a replacement it is accurate and looks great. Installed on a Holly 4150/4160.

looks great works great

Works good after realizing the common issue with fluid filled gauges. Installed on chevy 350, as engine got hot the fuel pressure on the gauge kept falling. With a little research I found that the little nipple vent is there for a reason. Once gauges get hot they will read lower pressure as pressure builds inside the gauge. This is why you can snip the tip of the nipple off or pull on the cap a little to let it breath once it's up to temp, this will let the gauge equalize with air pressure and read accurately. It's a common issue with ALL fluid filled gauges

Se ve muy bien en cuanto a manufactura. Sin embargo tiene una burbuja que ocupa un tercio de la carátula. Debo devolverlo?

Buena calidad, fácil de instalar y funcional. Es muy buena elección.

Me sorprendió la calidad de este artículo estoy totalmente satisfecho

Very good, works well

Do not buy! Used on calibrated pressure line at 36 pci. Reading is 32 psi. Useless item. Newer again from this brand. The cheap and simple Winters gauges - no one error for more than 20 units different sizes in past 3 years.
