When I try to remove the nut at the end of the compressor mounting (on the left black bracket) the whole nut and bolt spin and does not extract. Same for the other end. Can you tell by looking at this how they set it up? It looks like a stud into the exhaust manifold (silver/gray) then into the head (red). If the whole bolt or stud spins why does it not extract? I think I will have to make a special tool (half in open end ground to be thinner) so that I can grab the inner nut and hold it.

Oh and why are there two fuel lines as seen below? I assume the larger is the main supply and the the thinner is some kind of overflow return from the pump?

Comments?

Correct on both. Grind down a wrench, hold the inner nut (it's really part of the stud) and remove the outer nut.'

The large fuel line is the supply while the smaller one is fuel return.
