Default KSB solenoid leaking fuel

Well its not really the solenoid leaking its the brass piece in the end which I think is a check valve but I was wondering if it can be taken out and if it has an oring seal that needs to be replaced?Any help would be appreciated.

If you are looking at the pump from the front of the motor its on the side closest to the frame down closer to the bottom it has a selonoid just like the fuel shutoff selonoid and on the other end is a check valve it advances the timing during coldstarts.

Could you get a pictue of where it's leaking exactly?

crewcab59: it's on the right side (if your looking at the engine strait on) of the pump below the manual shut-off switch. It has one wire that should be connected and one fuel line. I think it's a fuel line haha. You can hear a difference in the engine if you unplug it right after start-up

To fix the leak your gona need to take a day and replace a seal in the top of your IP. If you don't already have a 3200RPM spring in your pump now would be a good time to do so. There only like $20 at max and make a world of difference! You're gona need the rebuild kit for the pump also. It's like $20 as well. Heres how to fix that seal.
