i know in 06 they changed them they have a different plug but all you got to do is swap conectors. im getting ready to do it to my 05. just bought a used 07 pump off ebay for $100. its probley gonna be cheaper and alot faster to just find a whole used fuel pump.
 
Here's the automotive part number for the pump.

"XB fuel pumps are made by Walbro and are model #521. Those pumps are used for older Ford mustangs among other very common vehicles. The pumps are available from a number of suppliers and are priced around $80-$90."
 
well on a whim i looked up 2003 ('03 bike) ford mustang v6 (auotzone, summit, oriellys, napa) and up pops a fuel pump which looks exactly like the bikes pump. I am going to autozone tonight to confirm and pick up the pump. pump includes screen which should still work and then gaskets for the mustang tank which i obviously wont use. for about 110 bucks. i need to get a replacement filter also so i will find out what works and let you know. and part number for the pump is E2366 if you want to take a look.

that 521 number looks like a 93 mustang fuel pump....which looks different to me. I'll see about comparing that one to at autozone.

Ok so.....(Drum roll).......it works!!!! I purchased the fuel pump for a 03 musntang V6, part number E2366 at autozone. It was 110 bucks plus a 4 dollars fuel filter. This number includes a strainer that is smaller than the stock one but seems to work just fine. All I had to do was take the pump assembly out take a bunch of pictures for ref on how it goes together and which wires go where, then disassemble it, and re-assemble it just as I took it apart. I reused the rubber seals on the steel filter nipples which just slid off and slid on the new filter. The wires simply connect to the filter just as they came of the old/bad pump. I did replace the steel clamp on one end of the pump with a normal hoseclamp because I ruined the original. Only thing that happened was when I was putting the pump back in the frame the O-rings rolled and were cut causing it to leak. So I need to replace those yet. The bike did start just fine and run for a few minutes no problem. So I'll have about 120-130 into replacing the fuel pump rather than over 300 for a whole new assembly...

have you had it on the road yet?3.8 v6 stang is around 38 psi on pressure buell is 49 psi.
 
Yeah, just took it out to rockford and all over around 80 miles or so and it ran great. Did around 80-85 up 39 for around 15-20 minutes and it did it without a hiccup. :) then even saw a black/red firebolt on the 90/39/51 highway south side of rockford. Even if there is a pressure diff in the pumps I didn't notice it. Maybe if it had a turbo there would be a problem....but I don't know, this worked for me and I'm happy with its performance and about 200 in savings.

ok well just a break down of the parts used....

Autozone for all parts (cheapest i found)

E2366 - fuel pump replacement kit (109.99)
8461_20110626223024_L.jpg

used pump, small strainer, and thats it i think.

FF3330 - fuel filter ($3.99)

?????? - o-ring kit that was stocked at my autozone that had multiple sizes in it. I used only two from it. they were the same diameter but one was orange and one was black. used these to seal the plate that gets bolted to the frame/tank. the originals were all loose and didn't seal well on the initial start up. these two seem to work fine. this was $8.99 i will add part number when i get it.

pump is kind of a pain to get back into the frame. i had to bend the strainer up to get it to clear the hole. I also used a little oil to lube the new o-rings on the plate so that they would slide in easier. i lightly tapped it in with the wooden handle of a hammer then once i could get the screws to grab i used them to pull it in in a criss/cross pattern and about 1/4 turn at a time. this seemed to work well. If you do this just take a bunch of pictures for reference before you disassembly it.
Thanks, Nick
 
I just went through this as well on my 05. This thread was pretty helpful. I did do a complete write up search for it. As far as the pressure differences, isn't that what the fuel pressure regulator is for? I'd guess the pump puts out more psi than 38psi and 49psi and the regulator in the car and bike limit it as needed. Not that I'm an expert...
 
I am so thankful that I found this post because I need to replace the fuel pump on my 04 XB12S. I will save me so much money than buying it from HD or ASB. My bikes header started getting red like it was running lean and the bike will randomly cut off like it wasn't getting fuel.
