FreeTec Vacuum Gauge, 10 PSI 70cmHg Low Pressure Fuel Pump Tester, Petrol Engine Carburetor Vacuum Gauge Vacuum Tester, Small Engine Fuel Pressure Tester Kit for Car Truck (Red)

Exactly what you need as a car owner who wants to get his own car right. Not sure this would be accurate enough for a professional but at this price, it can’t be beaten

Bought this to measure/set fuel pressure regulator in a (non injection) carburettor system. The gauge seems pretty well made and while I haven't benchmarked it against a previously calibrated gauge, it came up with readings that were in the expected ball park - so served my purpose. The accessories (rubber hose and plastic T piece in particular) reflect the (low) price point and are therefore very basic but do the job. If I were to use on a regular basis then would upgrade to brass fittings.

Had no issues with this kit. Been very useful for testing vacuum leaks on my old banger!

Nice piece of kit - well packaged and well supported by manual. Pleased with it.

Bought to detect a lean mix found an air leak within minutes great bit of kit at good value

Only comes with fittings for 5mm id. Mine like a lot of low pressure carbs has 8mil fuel pipe. Otherwise seems OK but it's early days.An adapter would be pennies if you're buying 000s so would have been a nice if they'd included one.

Seems accurate enough - used to measure pressure and vacuum so far.Did have to add a 3mm adapter to fit with my vacuum hoses, but for the price it's a bargain.

Bought to measure a low vacuum but found that the gauge would never return to '0' when disconnected: got a different no-vacuum value each time rendering the gauge totally useless. See photos. Returned for refund.
