New to MB TD/ got fuel leak

[AdamArc]

Hello all! I am new to the MB diesel world. I just picked up a 98 E300 TD. Great car! It has 176k miles with a salvage title. The car came with service records to 136k miles. So far I have had to reset the service light and cleared the a/c systems for good measure. The car developed a fuel leak that seams to be in the tank return line. The car runs great and leaves a small puddle in the driveway.

I've done some searching but there seem to be tons of info to go through. Most looks to be for older MB.

Any help would greatly appreciated!

Thanks Adam
