Well, you can see first, at left, Trumpeter's Sd.Kfz. 7 engine. The red arrow points to the hose I want to add, as I see in Griffon detail set
But, the 2 pics to the right (from Wheatcroft collection) show that hose entering directly into the engine, meanwhile the left pic, from Jamie's trip to Koblenz show the hose entering to a cilinder (like in Trumpeter's engine). I'm curious about that, how the same hose can go to 2 different part of an engine? Both cases are possible? Or I'm looking to the wrong hose in the gray HT?
Thanks
