I went to part store to buy fuel pump for my 2000 4wd 5.3 1500. Live in kansas and it was made in Missouri. It has the egr valve. They had like 3 different versions.

MU1089 MODULE KIT,F/TNK F/PMP

Can anyone help me out to figure out which one I have?? I know I have the T in my vin # but still confused about the robust fuel system and the evap emissions parts. What do I need to look for? Please let me know if you could help. I'll be sitting here kicking the tires untill then. Thanks

Best advice to be sure is remove the old one and take it in to compare, or call a dealer's parts dept and give them all the info, after they confirm your part # you can cross reference it with the cheaper auto parts store version, not good to tell the dealer your plan though, the dealer by me gets a bit out of shape about this.
Hope this helps.

I called the local dealer...:rofl: ... geezz.

You were right, he had a fit. I called to get the fuel pump and he quoted a price of 485.00. :rofl: I let him know I thought it was a little high and told him the price at the local parts store and asked why was it $200 higher. Parts store 280.00. He said he would check to see if he could match. He said best was 325.00. I said I would rather go with the parts store because money is money. He said good luck... and tried to get off the phone with me. I asked him for the part # and he said " I cant give it over the phone." I said what you got to be kidding me. I gave him a little speal about how if they werent so over priced they would have this problem. and if i was rich i would have gm put the pump in for me too. I mean I did buy the truck paying his salary in the first place. So all in alll he gave me the pump # and I went to the gm ac delco website and figured out what pump I need to buy off of ebay for 100+ or so dollars.

:disappoin GM what are we going to do with you?? Keep it up and you might go out of buisness.

And as for the evap emmisions, check infront of the gas tank. If you have a small box about the size of the gas tank in front the gas tank you have evap emmisions you need the mu 1089.

After you get the correct number check at http://www.ebay.com I have noticed new delco pumps much cheaper.

Stay away from Airtex for fuel pumps,they are a big piece of junk and will not warrenty a defective pump.My father put in 6 of them in a Chevy truck so far.Stay away from Autozone and advanced,you do not want to replace a lot.Carter has the best fuel pumps out there,they will warrenty a defective fuel pump and one more thing:replace the fuel filter too.That is part of the warrenty and it says on the box sometimes to replace the fuel filter also.

It may boil down to my moto.
Oem Dealer type parts only hurt one time.

Good Luck

I agree. OEM is the way to go when getting a fuel pump. The dependability is far better than the generic pumps such as Carter and Airtex. I perfer to replace a part with one that I know will last. The failure rates of generic pumps like Carter and Airtex are very high, and even if you can exchange the defective pump without much hassle, you still have to consider the work involved to change them out (removing the defective pump, making a trip to the parts store to get another one, hoping that they have it in stock, installing the new one, worrying everytime you drive if the new one will fail).

The only aftermarket pump that I would consider would be the Bosch. I've heard a lot of good things about them.

Before replacing the pump run a fuel pump pressure test to make sure it is bad and check grounds and 12 volt feed to fuel pump.
What is yours doing or not doing?

My father does put in Carter pumps and no comebacks.I know about fuel pumps from Autozone,junk.I talk bad about AutoZone and they should be called AutoJunk.Had to replace one and put in one from Carquest.The customer took it back to them for his money back.

Do you work for Carter? Everytime someone mentions fuel pumps, you pop in to talk about Carter. The odd thing is that your story keeps changing. Sometimes you say that you had 2 Carter pumps fail, and other times you say that you didn't have any pumps fail.

The reason some shops use brands like Carter is because they are cheap, and normally last until the 3 month warranty expires.

Quit getting fuel pumps from AutoZone!I hear all but problems with fuel pumps from AutoZone.There is another brand to stay away from,Airtex.Airtex makes fuel pumps for Napa and Carquest.Carquest just went to another supplier for fuel pumps and did away from Airtex.Carter makes the best fuel pumps,my father only had 2 go bad so far.I know about Airtex fuel pumps,put six of them in a row in a Chevy truck and warrenty claims denied.

I had two carter fuel pumps fail and they were covered under warrenty with the fuel filter changed,by Auto Value.A new fuel filter is part of the warrenty for Carter.A seperate,new set of wiring goes with a carter fuel pump.Airtex also makes fuel pumps for CarQuest and Carquest is dropping Airtex for making their fuel pumps and going to a differant manufacturer.Always change the fuel filter when changing the fuel pump.It is part of the warrenty

If your truck was equiped with the robust fuel system then the (RPO k53) will be listed on the build sheet (label) inside the glove box.
RPO means "regular production options"

Just my thoughts on pumps and other electrical parts. AC delco used to be made by delphi for many years. I have been told by several distributers and some repair shops that a couple years back delphi and delco contract ran out. gm now puts on bids to companies for cheapest prices. one service station told me he got a fuel pump for a car from gm dealer and the pump was actually stamped carter. gm warranties there part well but you pay for the warranty. If you want a good pump I would get a delphi, ive been told by many they have had no failures with them. Just my 2 cents of info. Oh by the way the gm pumps usually dont have much better warranty than aftermarket unless they install.

When I replaced the fuel pump in my truck, I bought it at Napa and it has a lifetime warranty.

Hello to all,
I can say from experience, you will make yourself mad if you have to drop that tank more than once in a two week period. I had to on a '88 chevy I once owned. I did not have enough help to slide the long wheelbase bed back for access to the fuel pump/sending unit assembly. I was blessed to own a good floor jack. Regards, HC2000:)
