Will a 2006 gas tank fit a 02 tank for a trailblazer?
Will 06 trailblazer tank fit a 02 trailblazer?
No! My friend ran into this a few months ago! I know 2001 thru 2005 Blazer is the same but within those years 2 door and 4 door body styles used different tanks as well! Your best bet is to visually match up the tank you have with one that you're looking to buy. Hope that helps! Jim
