Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

GM used these very small connectors and they were susceptible to problems. Most of our new fuel pumps come now with a different connector that has larger contacts. You basically have to cut the old connector off. You couldn't leave it on there. Cut the old connector off.

It comes with a new connector, which is all color coded: purple, gray, black, black with white stripe. So, we've cut these four off and we'll strip about a quarter of an inch off. Then these connectors are two different sizes. The blue ones are a little larger, so I'm going to use a blue one on the gray and the black wire. I put the connector on. There's metal inside. Make sure the metal gets down over where you've stripped, crimping pliers. I actually put the pliers on. Now take the wires and match up the colors and push them into those splices. Then just clamp it to lock the wire in. We'll fast forward as Mike does the rest of the wires.

Now wrap those splices in electrical tape. On some cars . you'll notice on this Monte Carlo that we did this procedure on . there will be posts in the way of this harness and you will have to remove one of those posts so that you can fit the harness in there.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video we're going to show you how to replace the fuel pump and sending unit on this 2002 Chevy Suburban with the 5.3 liter V8 engine. The items you'll need for this are a new fuel pump and sending unit from 1AAuto.com, 8 and 15 millimeter socket and ratchet with an extension, flat blade screwdriver, pry bar, pliers, hammer, an assistant, and jack and jack stands.

Start off by loosening these two hose clamps. It's that hose but we actually end up loosening the hose clamp that's up near the spare tire on the other end of the hose from where we pointed as you can see here. That'll make it a little bit easier when we actually get the tank down. Once you loosen those hose clamps, just pull those hoses free. You may need to use a pry bar to help get that free. You can also use a large flat blade screwdriver.

Now, you want to take a jack stand and just put it underneath your gas tank. Next you want to remove the gas tank straps. To do that, you want to remove this 15 millimeter bolt, and this one on the other strap. We'll just fast forward as Don does that. Now just pull that strap up and out of that slot. Do the same thing with the other one.

Now, have an assistant hold one end of the gas tank while you lower the jack and reposition it. On top of the gas tank, just pull this hose free from the bracket, and then go down to the end that's lowered. You'll see this hose. Just pull that free and then pull the hose from this bracket on the side of the tank. Then, do the same thing with the one below it. Then, you keep freeing those hoses by pulling out the brackets that line the tank. Now, on fuel pump and sending unit you'll want to just push the tabs and the harnesses and disconnect them. Then using a pair of pliers just push the tabs on this hose to pry the hose off. Just pull them free. Now, at the end of the gas tank closer to the front of the vehicle, you'll want to just pull these hoses out. Then, reach back behind here and just pull up on these hoses you disconnected from the fuel pump sending unit earlier. Using duct tape, just tape up the holes on the lower end of the gas tank. You removed those hoses at the beginning of the procedure. We want to make sure it has no leaks. Rremove the jack stand, lower the back end of the gas tank down. Just carefully slide it out. Then, you can set your gas tank down and then just disconnect this hose. If the gas tank is too heavy, just dump some of the gas out into the proper container.

Now, to remove this ring, you want to just lift up on this plastic tab on the side here and then, using a hammer and screwdriver you want to just twist that ring, making sure the that tab stays up. Once the ring breaks free, lift it up and over the sensor and pull it off. Now your fuel pump and sending unit are pulled out of the tank. You want to make sure that you drain the gas that's stored inside of it by just holding it upside down.

On the left is the old fuel pump and sending unit. On the right is the new one from 1A Auto. You can see that they're identical and they'll fit exactly the same. Push this arm into place and then you want to swap over these clips, just pry out on them and slide them off. Then slide them into place on your new sending unit.

Lower your new fuel pump and sending unit down into place. Put the ring back on. Then using a hammer and flat blade screwdriver, just hit it back into place.

Now, take the fuel tank and put the front end up first. Then, you can reconnect that hose in there that you can only really access when your tank's down. Then you just want to clip these hoses back into that bracket. Push that tank back up into place, not all the way because you still have some things to connect up there but pull them in there and then put the stand underneath it, with the back end lower than the front. Then push these hoses back into your sending unit. Reconnect those two harnesses. Then you just push these hoses back down into this bracket. Make sure you push them into the other bracket all the way up to the back of the tank. This goes back. Then push this hose back into place and re-clip it to the side of the tank. I will just fast forward as Don raises the tank the rest of the way back up. Now, you just want to remove that duct tape. Now, reconnect these two hoses and slide the hose clamps into place. Then just tighten them up with your socket and ratchet.

Slide the rear gas tank strap into this slot and then feed it up with the bolt in and tighten it up. Then repeat the process for the gas tank strap on the other side, and you're all set. We hope this video helps you out.
