OK, I have a 99 XLT with 4.6 V8. The truck died on me, I got it towed to a dealer 5 miles away, and the diagnostics says fuel pump, which is what I thought it was based on symptoms. Anyway, just got a message saying it would be $896 to replace. What?! That seems like a staggering amount to me. Is there some big deal with replacing the pump? I'm assuming it is on the gas tank, but haven't looked at the book. Give me some advice guys! Need to figure out what I'm doing by Monday. Thanks!

 

The fuel pump in INSIDE the fuel tank. As I sure you understand now, you have to drop the tank which is difficult at best, and if it has fuel in it even harder. The fuel pump can cost up to $200 and then add labor to that, OUCH. I've done it once and had help and it took several days. (no lift to work under) Good luck

 

I had a thought, take the bed off the truck and do it from the top. The bed is held on by 6 large bolts and without the tailgate it's not too heavy.

 

The pump is in the gas tank. Changing it requires you to drop the tank or remove the bed for axcess. its fairly straight forward and can be done in the driveway at home if your so inclined. The pump will set you back between $100/$200 depending on source and I would suggest you check the fuel pump drive modual located on a cross member above the spare tire, they are very prone to corrosion and failing

 

His '99 uses a different fuel delivery system, the FPDM is an '04 and up issue.

 

Moved to 97'-03' section.

 

800 dosnt seem too bad, the dealer quoted me at 1200 to do it. I ended up doing it myself and it wasn't too bad. I dropped the tank to do it, but if I did it again I would definitely pull the bed off. You will also need the quick connect tools to get the lines off.

 

If you have at least one friend willing to help you and a free day then you can easily change it yourself. Mine went out in January and with all the parts it cost me right at 200 to change it myself, I bought the complete fuel pump assembly from auto zone. Took 1 other person to take the bed off and I had 3 people helping put it back up and line it up. Got it done in 1 day

 

Changing the fuel pump is not a bad job if the tank is empty or nearly empty. If you have a half a tank of gas in it you have over 100 pounds to work with in removing it. If the tank is full, you really have to drain the tank of gas which can be a problem if you have no where to put it. As I said earlier, taking the tank off is easy if it is empty. If you have no place to put the gas and draining the tank is not possible, the only alternative is to have it towed to the dealer and let him do it or take off the bed. Taking off the bed has it's own set of problems with rusty bolts, help from friends to lift it off, and placing it somewhere. I had a friend who did neither when he cut a hole in his bed over the fuel tank where he could remove the fuel pump without removing the tank or the bed. After he was done he put a sheet metal patch over the hole.

I had to change the transmission fluid and filter on my car this week but two weeks ago I experienced some medical problems that make if very painful for me to work. As such, I took it in to the dealer. I previously purchased the filter and trans fluid spending around $30 and it was going to take me about an hour to do the job. When the dealer did it I had to pay him $154. Its good to remind myself every once in a while how much fun I have when I DIY when performing maintenance or repairs on my vehicles. You can't really fault the guy who wants to charge you $896 for the fuel pump because he is saving you a lot of problems and deserves to get paid for his trouble.

 

TAKE THE BED OFF??? Wow, thats a lot of work. Two bolts with a jack underneath. Lower it down just far enough to undo the lid. Don't unhook anything. You can pull the entire setup out without the tank on the ground just keep it supported. I have changed three pumps by myself doing it this way. $100 for a Walboro 255 off ebay, do your research,. Not that you need that much flow, just an example, good luck, fairly simple to do.
