DPTOOL 3/8" 1/2" Drive Diesel Injector Fuel Line Socket Wrench Set, Metric 8-22mm Flare Nut Socket Set, 14 piece 5-Point Avoid Wire Nut Socket for Wired Temperature Sensor, Thermo Switch, etc

Work great and works as suggested. Heavy duty. It has a good build quality.

Great set if this is what you are looking for. It comes in a nice quality case. Great to have in a tool collection. Good quality.

Bought these to remove direct injection fuel lines. Was able to make work for removing bmw fuel hardlines but.. was not able to get any reasonable torque to re-tighten them. If I remember correctly the torque spec was 25 ft lbs and at like 21 ft lbs the socket metal flexed and the socket skipped over. Anything under that they work pretty good. If the socket walls were a little thicker would have made all the difference not bad for the price though

These are well made sockets and should work well for fuel rail applications and some sensors. While you can sometimes get to these lines with a regular wrench, having 2 flats sometimes causes the wrench to slip. Having 5 sides with these sockets should allow more force to be distributed. I'm satisfied with them so far.

Not for tightening or loosening something beyond 10 ft lbs. I tried to use them to tighten this fuel line to 44 ft lbs. They just flexed and slipped around the nut.

cheap, metal flexes too much, dont buy

I say that next phrase often, but it was never more valid than it is now! This is a MUST have for any technician! I did a suspension job on a Mercedes recently where I had to replace the rear air springs. The fitting was recessed into a hole and in order to remove it you had two options. The first was to cut the air line and remove the spring with the fitting in it. Well, cutting air lines is not a good idea in general, there is not much extra of it. I asked two other techs how to tackle this and if they have a tool for it and all they came up with was flare wrenches, which would've never fit into that tight spot. Then I remembered that I purchased this kit and in that moment it was godsent. That turned out to be the only clean and proper way to remove that air line. It works for all other setups where you don't have the room around the fitting to use a regular wrench or socket. What impresses me as well is that they have every single size between 8mm and 22mm. That means that with the 17-22mm sockets you can even loosen strut nuts while preventing the shock piston from turning. I couldn't ask for more here!

haven't tried every size, but definitely handy for oddball sensors and other items. case is ok, but i'm running out of room for them and this one isn't that nice, probably stick these on a mag rail.
