Do any of the fuel pumps for1999 4dr Blazer have lifetime warranty?? If so which one & where to buy?

 

I understand your question but let me just say that a "lifetime warranty" is not the "end all problems" answer that you are seeking.
Plenty of pumps have a "lifetime" warranty. So you get a crappy fuel pump with a "lifetime" warranty. What happens if it goes out? Oh sure, they may just cheerfully exchange a broken pump for the exact same problematic pump while you also spend money on other things while in the store. Then you get to do the entire job again.
I recommend buying an OEM quality pump like an AC Delco and avoiding the "we will give you another one if it breaks" lifetime warranty scheme. Hope this helps you out.

 

That about sums it up! Get an AC Delco or Delphi unit.

 

The OEM fuel pump in my 99 Blazer lasted 100,000 miles with no problems,and I changed it out while it was still functioning (but just barely). I put a Delphi in it-this isn't a job I want to do very often-I don't want to be out in BFE and have a "bargain" fuel pump go bad-there's just no limping home-it's towtruck time.
