The number 1 injector on my backhoe is leaking out the return line fitting on the injector. I loosened it and then tightened it and that helped but its not dry. Is there an o-ring in there? My JD dealer wants to sell me a new line, but I'm thinking I might just need an o-ring. Anyone know what size it is? Thanks Dave
Most use a aluminum tee on top of the injector, little steel lines between injectors, square cut rubber compression seals, two sizes, big one on injector, little ones on the lines, if overtightened the aluminum will distort and you have to replace.
