New fuel pump making grinding sound.

Bought a nice 96 V6 and when sitting still engine idling noticed a very audible whine coming from the back, mechanic said it was the fuel pump going bad and with 115K miles on it should be replaced. Got a new fuel filter, pump and sock that goes over pump intake from Advance Auto Parts all cost about $110.00

Mechanic dropped the fuel tank and installed it, I watched and he put it in same way the old one came out and put the new sock filter on the pump and changed the fuel filter. Got the tank back in place with the rubber mats on top of the tank where they should be. Cranked it up and good to go, next day sitting still idling I noticed a grinding noise, opened the trunk and sure enough it was the new fuel filter grinding. It is not just a low pitched grinding and it is very audible.

The old pump was whining, this one makes entirely different grinding noise so went back to the mechanic and he said thought it might be bad bearings in the new pump. He said let him try something, he dropped the tank about a foot and cut up an old inner tube and made rubber insulation mats and put on top of tank and put one directly over the fuel filter hook ups on top.

Mounted the tank cranked it up and ecact same grinding noise. :shrug: He didn't charge me anything that time but charged $90. for the new pump installation. So, he maintains the bearings in the new pump are bad and in order to fix it must have a new pump. Lifetime waranty on the pump so no skin off my nose there, other than paying the mechanic to take the present one out and install the second new one. If he installs the new pump and the grinding stops that confirms it was a bad pump, DUH.

Now here's what ticks me off. I went to Advance Auto Parts and told the guy what went down and he said they would replace the pump. OK, no problem, but what about them paying the mechanics labor charge to take the defective pump out and put the other one in? Not my or the mechanics fault we got a bad pump and why should I have to pay labor charges TWICE because they sold me a defective pump? Guy said they don't have any provisions for paying labor to replace defective parts. So, looks like I'm strapped here and must get the new pump from them, but if another pump stops the grinding that confirms the pump was bad and if that is the case you can believe that is the last part I will ever buy from Advance Auto Parts.

OK, I take the mechanics bill to Advance Auto Parts and they pay 50%, but don't tell me I have to pay TWICE to replace a defective part they sold me. I messed up getting the pump myself and should have let the auto repair place get it, then they would eat the labor to replace it a second time.

Thanks for hearing my rant, your thoughts, comments and similar experiences appreciated. Ya'll have a nice week end. Huney
 
I agree it's not your fault the pump was bad but it's not Advanced Auto Parts fault either. Whoever made the pump is at fault so really AAP shouldn't have to pay either. I'd say just suck it up and either install the second one yourself since you watched how the first one got installed, or pay for it.

Either way, bad deal you got screwed with the double labor but it happens I guess.
 
I understand where you're coming from, BUT, my point is, AAP has recourse to the people who sold them the pump and I do not.

I've worked in Corporate America and know my way around and plan to write AAP home office and find out who sells them their pumps and advise them of my displeasure and also inform they lost a customer and I posted it on the internet.
Maybe it will save someone like myself from falling victim to a lousy pump maker because them shipping a pump grinding THAT loud tells me there is no way in h3ll it ever went through quality control or was on a functional test bench.
