Well the Blazer took a dump the other day, diagnosis, fuel pump, $212 later, plus $12 for a fuel filter, n the job was done in 3 hours, little slow because of the beer drinking n bench racing, only hard part was the rewiring of one connector, the old one had a gray, purple, and 2 black wires, the new one had gray, purple, black with white stripe, and solid black, used the old pump to figure out which black went to which black, can't remember what we did but all is good.
