Where is the fuel filter located on a Chevy Blazer?

Blaze fuel filter is UNDER the truck, on drivers side, on frame rail in front of left rear wheel. It is a In-Line Filer, you can get replacement at any Wally's Mart Auto parts department. If fuel lines are old and rusty DO NOT try to replace ot your self, as you could cause major fuel leaks. Get a professional to inspect the fuel lines.
