On my 94 S-10 4.3L pickup the filter was near or on the drivers side frame rail beneath the extra cab area. Probably similar in a Blazer. It was pretty easy to get to. Make sure to depressurize the system at the schraeder valve on the fuel rail under the hood before undoing the filter. On CPI motors the fuel pressure should be 60 psi key off. But CPIs usually don't start at all if the fuel pressure is a little low.
