2005 Chevrolet Silverado 2500 HD Q&A

2005 Chevrolet Silverado 2500 HD Question: How do I tell if my truck has an evaporative system on it.

I have to replace my fuel pump (it is putting out low pressures) but when I go to price out new pumps I keep getting asked if it has an evaporative system on it. I need to know how to tell if it has it or not. I hope not as those pumps are much less expensive. Thaks. -
Answer 1
All vehicles have an evaporative system, but they may be asking for something more specific. Try looking on the emissions sticker on the underside of the hood, or try looking here for some info: http://archives.media.gm.com/division/2005_prodinfo/chevrolet/trucks/silverado/index.html -
