I replaced the remaining orings, and I dotn see a drop of diesel anywhere, but I still have some bubles in the lines, I guess it will take time to clear those out. The car however is still the same, idles rough, and I can bearly get it up to 60mph on the highway ( i took it for a test drive ). I also noticed that the gears shift hard, especially from 2-3rd, there seems to be a loud bang comming from the rear of the car. Also, when I replaced the orings on the IP itself last weekend, i did remove few of the assemblies that the copper washer is sitting on. I will include a picture for referance.

Thanks again
