Hi All, I've owned my K5 1000 since 05. I had to mothball it several years ago due to financial, family, and business reasons but now I'm getting her back on the road!

My Fuel pump was stuck so I swapped it out for a Napa pump for the Mitsubishi Lancer. Required a few mods, but it fits well. I did however tear the O-ring part No: . 15113-35F00

Does anybody know what size this O-ring is? I'd also take the size of the O-ring on the fuel pressure regulator and the pump to tank seal as well. All of mine are swollen so I can't really get a measurement from them, and I tore the one for the pump. I have a bodgy fix for it right now, but my bike only runs good with a full tank of gas, so I really think I need the right rings!


BTW, I know I can buy that one, but it's over 7 bucks from Suzuki! And the big one to seal the tank to pump housing is 24 bucks!


Also, has anyone found a Fuel Pressure regulator by itself? Mine is rusty and I'd like to replace it if I could. I kreemed the tank already, but the FPR seems to only be available with the fuel filter assembly which I'm not buying. I did the external filter mod.


Thanks!
