Remove the TOP NUT on the injectors, that will allow u to remove the return line that's connecting all the lines together..
There a "copper" gasket UNDER that return rail.. REPLACE IT.
thepumpguysc,
There is not a copper gasket under the return fitting on these injectors, it's aluminum.
carp1, remove the top nut that will remove the hose barb return fitting, do not try and remove the aluminum washer, just use a deep socket and remove the injectors.
Sadly there isn't anyone local to us that I know of, that pop tests fuel injectors, they might be some in spokane.
But here is my logic.
By the time I spend a day and fuel to drive there, I'm better off to get new / rebuild ones.
I would say with the age of your tractor you would do well to get a new set, and they come with new sealing washers!
I get mine from
