Well, as the subject states I just Couldn't stand the Indian "paint" any more, it is not fuel or oil proof at all, it's not really even oxygen proof.
Anyway I took it apart and sand blasted every spec of this stuff of every part, while I had the wheels off I also did 38ac's balancing method drilling holes this time, which turned out perfectly.
I also drilled a two inch hole in the head to use as an oil pre heat system, the thread in the fuel line nuts is metric 14-1.5, I went to a local diesel fuel injection shop and had them make me two twelve inch lines with cones and nuts on each end and cut me one raw piece of line 24 inches long their line is one quarter inch OD one sixteenth inch ID.
The sealing cones are awesome on these lines, they kick the s#it out of the sorry ass Indian things, the cones are separate pieces and they silver solder them on he lines.
I then bought four grade eight 14-1.5 metric bolts making sure there was some straight unthreaded section on the bolts, the bolts were drilled out on the lathe and on the threaded end the hole was counter taper countersunk to match the cones on the lines.
A plate was then made to cover the hole with four holes in the corners to match drilled and tapped holes in the head, and two holes for the drilled out bolts/fuel fittings to pass through these were then tig welded on both sides to the plate with the taper counter sunk threaded portion on the side that would be outside of the head.
I made the twenty four inch long raw section of fuel line into a coil that would fit inside the two inch hole in the head, then drilled out the inside the head ends of the fuel bolt fittings just over one quarter inch so the ends of the coil would fit in these bores, I then tig welded the coil ends to the bolt ends.
Now the coil goes inside the head in direct contact with the cooling water and preheats my WVO before injection, since a picture is worthy a thousand words here are some of the parts.
