That is not a screw, that fuel line fitting hold the hard line tight to the IP. It could be the line is cracked. do you have all the metal clamps between all 5 hard lines? with out the clamps, the lines vibrate and eventually causing it to crack.

If not, loosened it at both ends and maybe repositioned it and see it helps. You might need a new line.


I just went back to relook at your picture. you have the "M" pump, came with the Euro models. might be a little difficult to find one of those lines. I now do see the clamp on the right side under a wire.
Not sure if a line from a "MW" pump will work, worth a try.
