Contraction question
Could someone please help me understand when not to use the definite article el with de? I have a Spanish dictionary and have came across quite a few instances where sometimes the contraction del is written, and others just de. Here are some examples.
correa del ventilador, filtro del aire, freno de disco, tubo de gasolina,
Why is that some have the del contraction and others just drop the article?

I do not agree with Chileno's answer.
That would be totally regional in my opinion. For example, I would use "de" for all your sentences. "Filtro de aire", "correa de ventilador"' etc.
gas line/tube = tubo de gasolina (any line/tube)
the gas line/tube = tubo de la gasolina (one in particular)
