17 pc Diesel Engine Compression Tester Kit Tool Set Automotive Compressor

It works as it should and fit properly and is a very useful and universal tester

Terrific case with a wide variety of tools to work on diesel engines at a very affordble price.

Bought to test old 1971 diesel Mercedes compression. I pulled out glow plugs and the adapter is so long that I could only fit into the last cylinder. Why is that size adapter sooooo long? I would have been much happier to use the adapter that threads I to glow plug hole than remove injectors. However, I did remove the injectors and another adaptor did indeed fit. Therefore this kit works with my diesel, but could have been better with a shorter adapter that was the same length as all the others.

I was sent a used set with the case tore up and melted on the inside, pieces are all scratched. looks to be in working order and I will see shortly just assumed would be new if not told it was used.......update, none of the fittings work for a ford 6.0 glow plug all are too small

Used this on a VW MK4 ALH engine. I had to remove the injector lines on a couple cylinders to get access. I'm very happy with this unit.

Great and economic kit and good delivery

I have been a mechanic for decades. I needed a diesel compression tester for my son’s vanagon. This was inexpensive so I figured why not.. on the second cylinder out of 4 the gauge would not hold pressure any more, rendering it useless. I bought this almost 2 years ago, but it has sat in my climate controlled garage on the shelf next to all my other specialty kits. I would have been further ahead just running to harbor freight and spending an extra $20. I saw other reviews said the same thing. It has a nice case and the pieces feel ok, just a terrible dial meter.

When I measured low compression I checked the gauge with a high pressure air pump, and it was dead on.
