hello all
On my 17 1500 big horn with 57k miles I got the dreaded P0463 code. “Fuel level sensor A circuit high”. I know there has been lots of talk about this code. The truck starts fine and runs just has the annoying check engine light with that code. Would this be ok to clear? Is it possible to accomplish changing the fuel pump without the truck being on a lift? I’m not looking forward to dropping the tank to change it but it that’s what needs done I will try it. I really don’t want to pay a shop to do it. lol. Thanks all.

You could loosen the bed and move it back to gain access to the pump ,if your model allows for it.
Or remove the bed to give yourself more room.

Check out our search engine , usually you can find helpful information.

I just did this job on my '12 It wasn't horrible to do.
Feel free to hit me up about issues.
I would recommend going to your local auto part store and getting Dorman Product 800-023 if you plan on detaching any fuel lines.
The description states it for Ford and chevy but its is a direct replacement for Ram fuel line clips.

Having replaced fuel pumps on both an '09 short bed crew cab and a '19 long (6') bed crew cab I'll tell you what I've learned. All this is for 4th gen gas only, I have no idea if the diesels or other gen trucks are the same or different. First, the fuel pump on short (5') bed trucks is right where the cab meets the bed. There's not enough room to remove the pump by pulling the bed. On those the tank has to be dropped. When I did that, I had to raise the truck about 3 or 4 inches AND remove my side steps to give me the clearance to drag the tank out from under the truck once it was free of the truck. But it was possible without a lift (POSSIBLE, not EASY). If you have a 6' or 8' bed, you should be able to get to the fuel pump by removing the bed. It should go without saying, but if you're dropping the tank, get as much fuel out as you can before starting the project. Also, cleanliness. There will likely be dirt and debris around the pump- get all you can off before loosening the ring and removing the old pump. You don't want any of that crap to end up in your tank when you're done. Be very careful & take your time with the fuel line clips, I found them easy to lose/break. Having replacements on hand as theblackduck suggests is a good idea.

If you can do it by taking off the bed, that'd be my recommendation. Even IF you have to drop the tank after the bed is off to clean out the tank for some reason. Access to and being able to see the various fuel line clips & connectors was so much easier with the bed off. Get 3 or 4 friends (or some heavy machinery-- I used a forklift) to help you lift the bed off. Using a forklift to remove the bed, I was able to do the entire job start to finish in under 2 hours.

If you have to drop the tank, be mindful of any external fuel lines running along the top of the tank when you go to lifting the tank back in. My '09 had several external lines at the top rear of the tank for vapor return and the rollover valve. You don't want to smash or break any of those lines as you lift the tank back in place. Ask me how I know :confused:

Another thing I would suggest is that if you have a Haynes repair manual, locate it......and then throw it away.
Nothing in that procedure was helpful in any way whatsoever...lol
I found more hidden fuel line attachments to that tank than that stupid book ever mentioned.
