Hello all,

Let me begin by saying that this forum rocks. I have learned so much from the guys on this forum. Thank you.

I have a quick question. I found a fuel leak on my 98 E300 TD. I believe it is coming fromthe delivery valve. I think I will need to change the Orings. How hard is it to change the Orings. Is there something that I should know before attempting to change it or is this something that you guys would recommend that a shop do?

Thanks
