 Round 2 with Pro DriveFinally got my engine up and running after rebuilding the carb. I was out running it a couple days ago and after about 5-7 minutes of running around 3900 RPM it would surge. The rpms would drop down to 3400 and surge between that and 3600. I reached down and pumped the bulb and it would go back to running properly. The bulb was about 1/2 to 3/4 full. Is this the indication that the fuel pump is starting to go out? Thanks Owen

Re: Round 2 with Pro Drive Sounds like u have a leak in your fuel line. But it also could be the fuel pump.

Re: Round 2 with Pro Drive Do you have quick connects on the fuel line?

Round 2 with Pro Drive Could be vapor lock, leak in the fuel line, or a faulty fuel pump.

Re: Round 2 with Pro Drive thanks for the input. I have a 2007 prodrive. Not 100% if it is CDI. I checked the fuel line and and the bulb, can't find a hole or leak in the fuel line. I guess I might replace the fuel pump. Should the bulb be full of fuel and all times?

Round 2 with Pro Drive Those cam driven fuel pumps suck. Do a search on here and look into puttin in an additional fuel pump, or call prodrive and ask what they recommend for a fuel pump.
