Fuel Economy Gauge Sunpro CP8221, Chrome Bezel, 2", backlit, incl. tube+fittings

Thank you come in handy

Sorta jerky reading not smoothNice looking gaugeHad to put a resistor in the dash lights wire to adjust the light output to match my dash light brightness

This gauge has saved me enough gas money to pay for the gauge. Buy one and try it you won't be disappointed.

The one gauge you should buy no matter what you drive, provided it has an internal combustion engine.

Kit comes with all hardware. However function of Guage is not the best. Does not register positive pressure. But should work for my needs.UPDATE: installed... the decell does not work, it is so sensitive that only idle is the best mpg reading.

nothing to say yet.

Very fast delivery! Quality is good and the instructions are very simple nice little gauge to have if you love MPGs

Basically a 30# vacuum gauge, red 0-10, green 10-20, yellow 20-30, helps keep your foot our of the pedal when accelerating up to speed or maintaining up hills.

Super awesome, install the nipple between carb and intake, not before the throttle body. It makes a difference when ur in gear and going, mines 100% accurate on my 06 hummer h3, 3.5L i5 engine
