DPTOOL 12pt 1/2" Dr L-Type Diesel Injector Line Socket Wrench Set 12 14 16 17 18 19mm (6PCS)

I bought these to do injector lines on a duramax. They worked just fine. Considering i might use these once or twice a year I think they are of acceptable quality and a good value.

Worked as needed. Thin head allows for access in tight spots and around fuel lines. Excellent for my tractors. Great value for a tool that sees occasional use.

Bought these to do injector crossover tubes on my 02 cummins. Worked great seems to be good quality.

Works good and must have to get around steel lines in tight areas

Perfect fit for the job just as pictured

Good heavy duty product

Perfect to us when pulling out my injectors on an Audi 3.0 TDI. Decent quality product. Fast shipping. No concerns of them possibly breaking. Fit great as labeled.

The tools look decently made for something that isn't used often or require much torque. And they fit in the case fairly well which is the only reason I'm giving it 2 stars.I'm replacing a fuel injector in a F250 6.7 which requires a 17mm line socket to remove the fuel line. I saw this set which was the same price as a single 17mm socket from a known brand so I rolled the dice...Unfortunately, it won't go over the high pressure fuel line "nut" so I can't get it off. I've come at it at every possible angle and tried lines that are much easier to get at, and it will not slide over the nut for whatever reason. I've looked to see if the fuel line could somehow be getting in the way but it isn't and something just has the wrong dimensions. If I had more time I would pull out the micrometers and try to figure it out but I have a truck that needs to be fixed first. Maybe the other sizes work? But if one doesn't I wouldn't want to rely on the rest functioning correctly.Maybe I got a dud but I don't see anything obvious and since they are cast I would assume the mold is off and this is not the only one that doesn't work...
