Keith Browning Posted November 18, 2011 Share Posted November 18, 2011 What are you guys using to torque the fuel injector lines on this engine? I am looking at a Snapp-On Socket, Flare Nut, 11/16", 6-Point... a crows foot looks like it might not fit the bill here. Quote Link to comment Share on other sites More sharing options...
mchan68 Posted November 18, 2011 Share Posted November 18, 2011 17mm Snap-On crow's foot on the one I just replaced. Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted November 19, 2011 Share Posted November 19, 2011 17mm crowsfoot but I'm not using a flare nut. I have a flare nut set but I bought the the open end just for those lines Quote Link to comment Share on other sites More sharing options...

Works very well ! and works good on the high pressure pump lines on the 6.4 as well http://buy1.snapon.com/catalog/item.asp?...amp;dir=catalog Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted November 19, 2011 Author Share Posted November 19, 2011 Thanks for the input guys. Steve, have you used BOTH a crows foot and the flare nut socket and if so, which works best in your opinion? BTW, his is really what I am after here.

Steve Mutter Posted November 19, 2011 Share Posted November 19, 2011 On the 6.7 I have only used the flare nut socket and I like it because you don't have to adjust your torque like you would with a crows foot. You just have to make sure the socket is clear of any other fuel lines when torquing, some fuel lines are close but will clear if the socket is in the right place.

Matt Saunoras Posted November 20, 2011 Share Posted November 20, 2011 Sorry I misread the thread. Keith I thought you meant flare nut like a crowsfoot flare nut socket. I've only ever used crowsfoot sockets on fuel lines I have one 18mm flarenut socket I use on power steering lines but the thought never occured to me to use a 17mm on fuel lines. I will definitely be trying this though. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted November 20, 2011 Author Share Posted November 20, 2011 Let's all get on the same page just in case we are confused about the terminology. The left image is a Flare Nut Crowfoot, the right image is a Flare Nut Socket. Typically I use a standard crowfoot for injectors on say a 6.4L because it works and allows me the ability to access the nuts on the injectors with the angles and clearances we have to deal with, especially with the cab on. Also, since we are not dealing with very high torque specs a flare nut crowfoot is not all that necessary and a standard crowfoot will do... Here, I am replacing injectors cab on through the wheel wells. I haven't performed injector replacement on a 6.7L yet and don't know if there are any clearance issues that would make either tool the better choice. Number one, I want to be able to do the job right and second, money is really tight and I don't want to spend $47 on a socket that is going to only take up space in my tool box and never get used.

joshbuys Posted November 20, 2011 Share Posted November 20, 2011 One of the guys I work with used to work at a indy diesel shop working on cummins, duramax, and power strokes, he has the flare nut socket and it works awesome on the injector lines and fuel rail supply lines on the 6.4l, I just can't bring myself to buy one for that much money...money's pretty tight here too!! Haven't had to do a 6.7L yet, but i'm sure it would make the job easy. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted December 3, 2011 Author Share Posted December 3, 2011 I remind you that I was replacing ALL of the fuel injectors, lines, pump and manifolds IN CHASSIS. A crow foot is not the tool of choice as it cannot reach all of the flare nuts - at least that is my determination. A co-worker had the M17 socket and it works much better.

Matt Saunoras Posted December 10, 2011 Share Posted December 10, 2011 Just did my first injector on the vehicle and a 17 flare nut socket would be perfect, though I used a crowsfoot because that's all I had it does tell you to use a flare nut socket in the wsm.
