Blazer Trailblazer?
 

I have a 2001 (Trailblazer). Are fuel parts from a 2001 (Blazer) interchangable. Im talking like - fuel filler hose, vent valve, purge valve, canister ect. I bought a new fuel pump and was hoping to get any extras from the bone yard. Im new at this. Thanks for any help.

Until the introduction of the new GMT 360/370 platform in model year 2002, a Trailblazer was just a trim level on a S-series Blazer. All mechanical parts are the same.

Thanks rriddle3 thats very good news. Being a carpenter and not a mech made your info very helpful.
