The return line should get rid of air in the system for you. air will
either
escape in the cylinder, or return to the tank.

Subject: Re: [Biofuel] Running on B100
Following another post (no subject) it could be that I have this all
wrong
and that there is air trapped inside the injectors somewhere, although I
don't think so as I bled out the system with brand new filters, so, by
default, the problem is at the tank end (maybe?). I shall soon see as I
am
having a Mercedes mechanic give it the twice over to determine EXACTLY
what
the boo boo is, and I shall be posting the results.
I share you latitude thing (not quite as north as Edmonton)although no
snow
quite yet we did hit the freezing mark a couple of times so far and it is
all down hill from here. **snow is a four letter word**
Anyway, stay tuned. As far as the changing os the filters goes, the
information on JtF states that after a couple of tank fulls of B100 to
expect to have to change them, and that would be about right for me as I
have run several tank fulls. although having a can type secondary filter
it
takes longer to fill up than the straight in-line type, so I was under
the
impression that that was the problem so I changed the secondary as the
primary did not seem clogged (I put air to it in reverse and got nothing
but
clean fuel). However, I still want to change the lines and flush the tank
out regardless, as I am sure nothing like this has ever been done in the
Benz's 21 years of life, so a good "enema" is overdue.
