Several times during the rebuild process, the fuel line near the fuel pump was leaking fuel. I would put the lines back on again nice and tight and it would work without leaks. Then after about a day sit, it would just start leaking again. Replaced the fuel lines, worked fine for a couple of days then started leaking again. Changed clamp types to the screw down clamps and it worked yesterday great for about 20 miles. Parked it, still no leaking. Started it up this morning and it is leaking again.
Also, it is idling well, but rough occasionally. I am thinking that a couple of tanks of gas through it with Sea Foam will get rid of the issue. Thoughts? |

Stewie. Oh, bsod.
It sounds like you are not dealing with where the leak is coming from. Trace it back to the source. It may run down the line, but come from somewhere else. Good luck. dc I found it, it was hiding under the fuel pump holder. Fuel pump leaks around the seams. |

It's difficult for me to see what I am seeing here. What year, make and model of bike is this?
It looks like the pump is in a 2 part housing, that has some type of ring connector to hold the 2 parts together. The connector ring appears to have notches in it that suggest unthreading it and taking it apart for a rebuild, which would include an o-ring where the joiner ring threads back on. Some sealer on there would be the easiest. I don't know which would be the best, some silicon or your rtv, blue or black or one of them is meant for fuel situations so the fuel doesn't disintegrate it. But you may be getting ready for a full fuel pump failure, causing a rebuild or replacement. dc |

Ok, so here be the update:
On the advise of a local mc mechanic, went and picked up some Instant Steel putty. Put it around the seal, and this shit works fast, 10 minutes and it was hard as a rock. I took it up to the station for a gas top off, so I could add cleaner, and at higher RPMs, ran like a champ. At lower RPMs, it chugged. When coming to a stop, it would die on full choke. I know the carbs are clean because we did a full dip on the part and clean. Spark plugs are new. Any thoughts? |

You gotta start with the basics. Spark and fuel supply. And anyplace where work was done.
Also, if you did a carb rebuild, that would be a place to start, anyplace you did any work. If those carbs have the flow too low or too high, you may have a problem like that. Could be the carbs need an adjust, or a sync. But also, could be the leak at the fuel pump is an indication that it's losing pressure and just about out of commission. You may have to turn this over to your local mechanic for a final tuning. Good luck and let us know how it goes. dc |
