I have an '03, bought just last year, and not sure if it was ever changed. It had 45K miles when I changed it, and once I got the new one, I could see that the old one had shrunk considerably! I stretched it and hairline cracks were all over it! It was definitely time for a new one.

Make sure you check the rubber gasket that goes between the fuel pump and tank - I put my original one back in, put it all back together, mounted it on the bike, put some gas to check it out, and it was leaking! Hard to tell that the gasket was bad, but it was - It's worth the $6 to get a new one; just make sure everything is clean and dry when reinstalling.

Interesting. I bought a set of strap wrenches from Autozone for not much money. There were two sizes and both had rubber straps. The large size fit perfectly and removed the ring nut with no damage at all to the nut. And I cleaned up the gasket and used it again and tightened the ring nut snugly with the strap wrench and no leaks after 2,000 miles of riding.

There was plenty of room for the strap to get a good purchase on the ring nut.

I have the big nut off, but I wiggled the pump up and it seems stuck. Any special technique to remove the pump from the tank?

Thanks in advance.

PS: I figured it out: use a small flat blade screwdriver (about 1/8 inch wide) and VERY gently, pry between the pump plastic (black) and the tank plastic housing (white nylon I guess). Go around a few times and voila!, the pump will come off. It has a big indexing protrusion: very easy to put back.

Big nut is off, how do you remove the pump?

Re: fuel pump retaining nut removal

About a year ago, I was having a problem with the fuel pump gasket slowly leaking after a filter replacement. I did buy (2 in a package) strap wrenches from HF for less than $10. Had it off several times trying to correct the leak, using several different approaches lube, dry, etc. Finally I read on here somewhere where it was stated that if you are having a problem with that seal, just buy a new gasket. Problem solved. The old gasket cleaned up looked good to me, but it sure wasn't.

I use something similar to this.

Re: fuel pump retaining nut removal

I used a cheap oil filter wrench which is a handle with a piece of roller chain on it. Wrap the chain around the nut and hook it over the hook on the handle.

I'll echo Curtis' comments as well. The gasket is between the pump flange and the tank. Just make sure that it is spotless and the flange that faces it is also clean. Then assemble it DRY but I always add a small amount of lube between the nut and the metal flange. This helps the nut slide over the flange when tightening it.

Still using my original one atter 80K+miles. Just inspect the rubber washer for nicks, gouges, tears.... If it looks good, use it.

Easy does it. Has always worked for me, having done it many times.

Or... a strap wrench if you have one.

Or.... Make a strap wrench by taking a strip of leather (old belt?) or non-stretching plastic and grip it with a ViseGrip.

That's pretty cool. I just went to Lowes and bought the strap wrench.
