Not sure which motor he has; but I think his truck is about 3-5 years old??? The tube didn’t break at the clamp; it developed a hairline crack right at the edge of the sleeve/ferrule that slightly extends outside of the nut.
Yes, we bent the krap out of the replacement tube to make it work. That steel tube is a heavy wall variety and didn’t take to bending, but we did a lot of prying, beating and twisting to make it work or we would have been on the side of the interstate until Monday. The long story is we ended up with the wrong replacement tube. We needed #4 and we got something else. It was much longer and could not be bent to fit. We pulled the next fuel line and bent it to go into the #4 fuel rail hole and bent the replacement to go between the remaining injector and fuel rail hole. In other words, they crossed. Anyway, they worked and we drove on to Silverton, Colorado and then back to Alabama with the re-engineered tubes. Never underestimate the tenacity of a bunch of offroad folks stuck on the side of the interstate on Saturday night while headed to the Rockies for two weeks of Jeepin’.
I omitted the part about first taking the cracked tube to a local “expert” welder to be TIG’s. He determined that brazing would be “better”. That repair lasted about 6 miles.
My buddy picked up replacement tubes in Durango on the way out and replaced them when he got back home.
