Replacing 2007 Mahindra 4500 injection line

Hello, I'm having a problem and need some advice. I have to replace the rearmost #3 injection line due to pitting at the injector with a failed connector. Could not get the leaking stopped. There is a small space between the air intake manifold and head but not sure if the space is large enough to pass the new fitting through without removing or loosening the intake manifold for extra clearance. Is this possible or is there some trick to it? Between the bright sun and sweat flooding into my eyes it is hard to see and seeking advice before disassembling the intake. I couldn't get the old line out without cutting it into two pieces. So is it possible to fit the new injection line from the top or bottom? Thank you very much.
 
Updated; 12mm needed to loosen manifold. Doesn't have to be removed just loosened enough to allow the end fitting between the head and manifold. Be sure to loosen the stud under the ground strap. All the rest are 12mm nuts.

Repaired and back to mowing.
 
I hope you realize that's awfully risky. If you broke the bond between the manifold and the head, you risk having an air (and dirt) leak at any of the ports now. I would strongly recommend you go over all the joints with engine running at low RPM and carefully spray some ether around all those joints now to make sure none of them could be leaking.

If you introduced a leak there, you won't "see" it now, but you'll "feel" it later.
