Your cart is empty.Actron's CP7803 Vacuum and Fuel Pressure Tester Kit is a great way to fine tune carburetion and timing for peak performance and maximum fuel economy. Use to test fuel pump pressure, mechanical condition of the engine, vacuum control system function, and much more. This versatile tool finds intake manifold leaks, blown manifold and head gaskets, worn piston rings, burned valves, and leaking vacuum lines on conventional and computer-controlled vehicles. The easy-to-read, 3-1/2 inch diameter gauge face displays 0-30 inches vacuum (0-70cm) and 0-10 pounds (0-70 kPs) of pressure in both standard and metric scales. Includes gauge, hose, multiple adapters, and detailed usage and testing instructions. NOTE: fuel system functions are for carbureted engines only - not for use on fuel injected vehicles..

Decent gauge. Actron usually makes decent tools. Easy to read and works properly. Haven't tried the pressure side tho. Not many mechanical fuel pumps around in 2024. Still nice to have this feature.

NOTE: THE FUEL PRESSURE GAUGE IN THIS UNIT IS NOT FOR MODERN FUEL INJECTED VEHICLES. ONLY FOR LOW PRESSURE SYSTEMS This gauge was very poorly packaged by Amazon for shipping. It was thrown in a box loose with one other item with minimal "Air Baggies" . It was able to bounce around in the box. I believe the gauge was damaged during shipping causing it to have a +2 PSI offset at zero pressure or vacuum. The gauge does not have any adjustment screw. I did return the item to Amazon and they quickly refunded my money. I will try to find it locally.This was the third Vacuum/Fuel Pressure gauge I ordered from Amazon (the other 2 were from Lisle Tools). Both of these were also packaged poorly and damaged and did not work properly. I am done purchasing delicate items from Amazon.Otherwise the gauge was very nice. Had a large face and comes with a few basic adapters and a hose. I tested it with a vacuum pump and it operated well except for the offset mentioned above. I will buy it again if I can find it locally.

I've been needing one of these for years to set up carburetors . Now I can get the correct power valve without the guess work .

Replaced the old one I had, was the same brand. Great for setting up carburetors and doing some fine tuning on a car or moyercycle.

El vacuometro No venía bien empaquetado ni protegido, por lo que llegó golpeado y descalibrado, por lo que no funcionó, deberían de tener más cuidado y empaquetar mejor los artículos para que no se golpen en el trayecto.

Bueno pero los accesorios dejan que desear igual deberían incluir otros o mejorar la calidad de las mismas pero trabaja bien

This vacuum gauge is perfect for adjusting carburetors to achieve maximum manifold vacuum, which increases efficiency and in turn... MPG!Honestly, there are thousands of uses for it, but my main purpose for buying it was to adjust the carburetors on my pre-'80's cars/trucks.The gauge dial is very accurate out of the box, as I have tested it against a known vacuum pull. Adapters and included hose are adequate for most testing purposes, but can easily be expanded with a few bucks spent here on Amazon or your local auto-parts store.If you need to measure vacuum pressure, you need this kit.

Terrific little device at a great price! I was having so much trouble diagnosing my car's flooding problem. This gauge told me everything I needed to know. Nice, big dial, easy to use. It wasn't easy to find a gauge that accurately measured in the low end of the pressure range. If you have an old car with a mechanical fuel pump, this is your gauge.Two things kept me from giving it 5 stars. It took a LONG time to get here. Amazon is usually so fast. Second (and this is minor), It would be nice if it came with some kind of a case.
