A 10 Warthog Engine trouble

Im re-building my old Revell -monogram 1/72 A-10 Snap kit , and have totally detailed it succesfully, inside and out. But now that the scratchbuilding is done, painting has become a problem. I have no idea what colour the various components in the A 10 engine are? Any suggestions, some colour recommendations would be awsome…such as cable,fuel lines, etc.

These pictures should help some:
