My fuel pump just died. Also, mechanic says some kind of related assembly has rotted away and needs replacing. He says this assembly is a known issue with Blazers. Says he has to go to a dealer for this part. Any idea how much this assembly goes for ?

150 for the sending unit, 150 for the fuel pump, and yes, it is a know issue, mine was just replaced 5 months ago.

Hell, I only paid 80 at the dealer (us) for my fuel pump at the dealership..Though the sending unit (what he's talking about) is almost 300 bux

These are now being made by the aftermarket, still not cheap. Check on www.rockauto.com for a listing.

You made out good. Parts I had replaced are below:

25168316 fuel tank sender.
25163473 fuel pump.
25168246 strainer.

The sender retails for $405 and unfortunately that is what I had to pay ( although if I was able to go without a vehicle for a week, could have been had for $220 from gmpartsdirect.com). The whole job wound up costing me $800 !!

Mine was 800 and they replaced the fuel tank as well.

They are overcharging you.
