Injector lines

Tyler Jackson · Jun 30, 2011

Well i posted this on the general tractor forum but I need to know this by 6 tomorrow morning so I can fix it. Our 01 NH tl80 bailing tractor that needs to do 40 acres of straw tomorrow started leaking diesel out of the sensor under the fuel filter. Took off the sensor most of the way and saw that the oring that keeps it from leaking has a large chunk missing from it, sooo tomorrow morning I'm going to get a new fuel fitler and oring from the parts place before the straw needs to be bailed. I have to bleed the lines after this and the service guy said to bleed the lines up to the filter then crack open the injector lines and bled them there. My question is how tight do I need to tighten the lines back to? just snug or tight or is there some kinda torque?

I always tighten mine snug and re-check them. I would rather have to re-tighten one a little later than twist off a line. Good Luck

You shouldn't have to bleed the injector lines just because you change a fuel filter.

a tight snug fit, tight enough so they dont leak.

Most injectors I have dealt with have a flare fitting so it doesn't take much tightening. On most modern tractors all you have to do is prime the pump and filters and they will push the excess air out the injectors. I would guess he said to crack the lines to be sure they didn't air lock???

What Allan said, Just to change the filters you dont need to bleed the injector lines. Change the filters, prime them with fuel and you should be good to go. Give the tractor a crank, if it starts you dont need to crack them, if it doesn't give one or two of them a crack.
