Lang ToolsTU-32-21 Compucheck Fuel System Restriction Test Gauge, One Size

The picture and description is correct for this test gauge. It is a vacuum gauge, used to measure fuel restriction leading into the fuel pump on a diesel engine. There is a male quick connect port that is included with the gauge. We did not need to install the port as our engine already had test ports factory installed. Gauge is a nice, large size that allows weak eyes like mine to accurately read it. Gauge is well protected with an additional rubber like device surrounding the side of the gauge. Coupler works just as it should, drip free connect/disconnect. This gauge allows us to quickly check fuel filter condition and check for fuel inlet line restrictions.

I have bad sciatic pain and this helps relieve it. I workout 6 days a week so it is good for all my sore muscles and use it daily.

Excellent tools

Ordered gauge it came box not damaged found gauge needle at 25 inhg not at zero got a second one and you can see it’s not at zero sent the second one back for refund . I will end up making my own setup . China junk

You have the wrong product on picture, you should only show gauge and compucheck fitting only for this restriction kit , the item your showing a different kit that is more expensive and comes complete with most adapters for testing older international engines which is part number Tu-32-3 also from Lang Tools. This kit comes also with o-100 psi pressure gauge. You should correct this item presentation.

The photo is misleading. Read closely, you get a single hose with a gauge on one end and a female compucheck fitting on the other. This wasn't enough to check fuel restriction for us. We needed to adapt the hose/coupler configuration. Not Happy!
