RE: Code 4726 (09-10-2020 )Mr Hagg Wrote: Ok so we remove banjo bolt and take a place a bolt the same size as the banjo bolt and use washers and the ones that come off the banjo bolt tighten it up and then start truck see if you see ANY fuel dripping out its bad... Then with insight run up fuel pressure through the fuel pressure leak down test... Onces it reaches 29000 turn truck off and see if its leaking. If not then you will need to start capping off injectors one at a time. A few times I have found the injector connecting tube is the problem may have worked loosed or what ever. So before I throw a $1000 injector at it, I will inspect connector tube and clean and reinstall and torque to spec.... And try again... If that dont work then replace injector + a new connector tube. NOTE: the caps can be bought from any cummins dealer.. I have all 6 so you can cap off as many as needed.... A video of this would be extremely helpful. I don't really understand the bolt in place of the banjo bolt thing. | |||
