Hello,

Ive been considering doing a diesel purge on my 83 240d. The only aspect that confuses me is that both the supply and return go to the same bottle.

Wouldn't it be better to send the return line, with its soot and other crud, to a separate bottle? Using one bottle-after a few minutes wouldn't you be sending some crud back up the supply line? Is there a reason to use one container?

Im sorry if Im just confused about how this works. Ive never seen this question come up and I cant help wondering. Any thoughts?

Thanks for any info about this!
