vector gravity feed to the carb went out with WW1. A fuel pump was always used as liquid can not run 'uphill' from wing or fuselage seat area fuel tanks.

What happens to fuel when put into the main barrel of the carb? The fuel is vapourized. So if a fuel line is cut in the radial engine's area, that high speed of air will do the same thing, vapourize or mist the fuel which will then burst into flame on the hot exhaust manifold.

"He said that almost every FW he hit from behind started to pour a dense black smoke which was obviously caused by burning oil. "

sorry man any hick knows oil burns white. gas and diesel burn black.

you get a hit in engine if oil hits the manifold or ignights its is a dense white smoke. been there

you run fuel rich its a black smoke usualy much less billowy.

If I'm not mistaken oil ignites at a lower temperature than gas. So as long as there isn't an ignition source (i.e. spark) the oil would catch on fire from heat before any gas would.
