I have a small problem. My braided fuel lines seem to be leaking. They are constantly wet with fuel between the 2-3 and 3-4 injectors. The short plug line on the #4 is actually dripping at a regular rate.

Can I replace these with regular, rubber fuel lines or must I use the braided lines? Should I re-plug the open end of the #4 with the MB plug? Or can I use alternate methods? I've got to stop this fuel waste.... Diesel is EXPENSIVE compared to the past few months!

The car is running fine except for poor MPG and a stutter at high RPM's. I am probably losing about 2 gal per tank on the ground! Any help would be great. Thanks in advance
