Leaking Carburetors ?
My fuel pump quit on my 2001 Voyager. I replaced it with a direct aftermarket fuel pump and installed an OE fuel filter and hoses. I turned on the ignition key, bumped the start button, and the fuel pump primed, and shut off as it should. I then cranked the engine and it ran well. Now for the problem. I have a fuel leak at the carburetor and I can't tell where the leak is coming from. It only leaks fuel when the engine is running. My guess is possibly the t-fitting the fuel line attaches to is cracked or the o-rings between the end of the fittings were disturbed and now leaking. Has anyone had a similar problem while performing the same service and if so, what was the problem?

Re: Leaking Carburetors ?
Larry,do you know the operating pressure of the fuel pump you installed
The pressure should be in the 3-5 psi range or you could be over powering the floats ability to shut off the fuel flow off.
You also may have accidentally got a small bit of dirt in the line causing the float valve to not seal,in which case, draining the bowls and restarting the pump may flush it out
A Seafoam treatment may also clean it out.
Let us know what you find.

Re: Leaking Carburetors ?
I have not had to change a fuel pump, but I did have a fuel leak which only happened while the engine was running. It was a stuck carb float. A couple taps on the float bowl, with a 3/8 extension, fixed it. Only TAPS. Bike outside, on the center stand, and a fire extinguisher please. One bowl at a time. Best wishes, tunnelz

Re: Leaking Carburetors ?
I didn't run the engine very long as it is inside my garage on the lift so I never let it run long enough to do anything except verify the leak. You may be right about the fuel needle and seat as I did have a lot of debris in the fuel filter and line. I'm assuming from the defective fuel pump. I don't know the operating PSI of the pump but a search on Amazon under the OE part number brought up this pump with the Voyager listed as a correct fitment. I'll take it outside in the next few days and drain each bowl and tap the side of the carb and hope for the best. I've not ridden this bike much in the last few years so I'll hope for the best.

Re: Leaking Carburetors ?
What was wrong with the original pump. Did you try cleaning up the points ? Most of the time that’s all that goes wrong with these pumps. Instructions on this sight.

The original fuel pump quit working and I've already thrown it away. The fuel isn't coming out of the overflow so I thinking its not the needle and seat either. I need to confirm but I think maybe o-ring fuel fittings.
