Of course....

Stands to reason. Put some boiling water into a metal vessel, whose metal mass is large, in comparison with water volume (like an injector attached to a huge iron/ally heatsink filled with cold water, thats the head)--and the water will cool, VERY quickly.

Simple thermodynamics.

Oil has HALF the latent heat capacity of water exasibating the issue. (So you would need Twice the amount of oil to heat up a specific volume of metal a specific number of degrees in comparison to water)

Try it yourself--Dont go believng a voice behind a keyboard--

With an old head and injector. Arrange a blow-lamp to heat the injector line, (Which will get infinately hotter than any silly elect powered 'line-heater') and pump fuel through the injector with a pop-tester.

--Not Forgetting a Pop tester pumps MUCH more fuel per stroke than in a real working engine

Measure the temp of fuel emitted from injector...

I did this test well over 15 years ago. There was little heat left in the fuel actually Injected.

Why is it, Twin Tank Conversions -on the whole- Work reliably....

While Single tank Conversions--Can and do--Cause Ring-Gumming and other issues??

Because the Cyl. Head AND the Injector are HOT before veggy hits them, and therefore a better atomisation and combustion occur, as the fuel is Heated whilst In the hot Injector!
