Re: [diesel_mercedes] fuel filter woes

You loosen the top filter bolt enough to spin off filter.I fill the new filter with Seafoam or Marvel Mystery Oil to clean injection.That way no need to prime.I check and clean primary every 250 miles when I have the little black stuff,and blow the line back to the tank to clear the screen.

Hi all,

I was checking the filters on my 300D and noticed dark stuff in the
small filter. I changed this filter and the one that looks like a oil
filter. I know about priming the system and I did that. However I
could not get the car started. This caused the starter to go and I
finally got a replacement in there. Whew! That top bolt is tough to
get out but I used a 20" extension and a knuckle (3/8" drive). I just
got it in and I got it to crank. So I am pretty happy at the moment.

So back to priming. When I did this, I first loosened the large spin
on filter and began to use the hand pump. Fuel came out of the filter
and also the pump body itself. Is this right? Could some one list
the proper way to prime. In the manual it says your basically
listening for air to escape but no mention of fuel flooding out the
pump. And how often and how long to crank the starter?
Thanks!
Jeff
