You've got quite a bit of leakage occuring above your red arrow suggesting your leak may come from above the shutoff valve. Check the 6 delivery valves on the top of the IP and confirm the leak doesnt originate there.

Your fuel lines are not crystal clear and may also be leaking. You can buy new fuel lines or o-ring seals only (search under my name for "606.962 o-ring sizes") for the sizes/counts if you go that route. Also search JADAVIS name, he is selling numerous o-rings in viton on his website.

Be very careful wiht the electrical connector on the shutoff valve. If it goes on and off too many times it wont connect properly and you WILL be buying a new shut off valve AND a complete engine wiring harness which will fly here from germany (rather not say how I know that). At this time, unless you are having shutdown problems that you didnt mention, you will only need a new oring to seal the valve to the side of the IP. There is no need to remove the electrical connector to do that job.
