I have a 95 CBR 600 F3 with about 21000 mile that is leaking fuel. All of the lines seem to be connected right and dont seem to be loose, or anything, but I tried to run it out of gas, and left the fuel flow valve off, and ran it for 45 min and it wouldnt die. It has a somewhat steady dribble off of what looks to be the fuel pump. I fear the casing on the fuel pump might be the problem. Should I replace the fuel pump to stop the leak, or is that not the problem? Any help or suggestions would be greatly appreciated.

 

i would say probably a bad seal around the fuel pump, make sure and check the fuel lines for any cracks on the ends, kind of frayed and replace them if you decide to change the pump, it doesnt sound like the pump is bad, but if your goin to remove it and it's not very expensive, i would replace it, basically your call, make sure everything is spotless before installation to avoid any future problems

 

Without being able to see it I couldn't tell you. But if I were to take a guess I'd say its a leaking connection at a hose joint, or maybe a cracked hose that is dripping down the hose and appearing to leak at the pump. I would try replacing the fuel lines first, especially if they are old. It's a cheap fix and may save you from trouble shooting any further. If they are original they could probably do with being replaced anyhow. I just replaced the ones on my '99 F4 cause they werent in top notch condition and my bike is always garaged and out of the elements...its really up to you, but my motto when it comes to trial and error troubleshooting is cheapest fixes first and go from there.
