m35a2 leaking manifold heater injector

[barnyardengineering]

Hi new to the site I recently purchased a 1970 m35a2 with a Hercules multi fuel motor. I noticed a small amount of smoke from around the turbo and seen that the back side of the heater injector was leaking where the snap ring apparently holds the end cap in is this common is it a simple take off replace o ring or should I try to find a replacement injector . Also if I take apart will I have to bleed the fuel system?

had the same problem with one of mine. went to my parker store and got new o rings. make sure to get the right rubber for diesel or whatever type of fuel you use. also treat the manifold injector like a main injector [keep it clean]
