[SEL] Hot tube material

[Vivas1993 at aol.com]

Hi folks,
 The hot tube in a FM Y engine is quite a bit different than the tubes used 
in oil field engines. I have a 25 FM Y, and the tube isn't any more than about 
2 1/2" long, and I think it's either 1/2" or 3/4" pipe thread, if my memory is 
working correctly. 
 The tube is heated with a blow lamp, and after the engine is started the 
lamp is taken away. There should be enough heat in the combustion chamber to keep 
the engine running on kero. or diesel fuel without the use of the lamp.
 I'm not sure of the material the tube is made of, but it looks like a type 
of nickel or stainless steel.
