I keep getting air at the middle injector nut during bleeding. The two
outside injectors bled the air and only fuel comes out.
This is a 3-cyl Mitsubishi and here is what I have tried. Replaced the
delivery valve o-rings twice, once from my Harbor Freight box of o-rings,
then I ordered and
Leaking lift pump.

And that would show up on only one cylinder?
I was thinking delivery valve or injector.
One could swap them around, see if the problem moves.

I think that the injector might need rebuilding. Compression from the
cylinder coming back into the injector because of a problem with the
nozzle not shutting or spring pressure too low. Try taking one from one
of the other engines you have and use it. Shouldn't take very long to do
that.
