In order to keep the two fuels from mixing when two tanks and filters are used the "banjo bolt" in the top of the stock fuel filter must be plugged from the bottom. Typically a small amount of JB Weld epoxy is used for this purpose after the bolt interior is thoroughly cleaned with alcohol to remove any residual diesel fuel.

The problems relate more to the physical placement, rather than sizing of the fittings.
It is going to be a real PITA getting the hoses fitting at the right length so that the banjo bolt is close to lining up with the IP inlet.

The banjo bolt is the part pictured. It is located in the top of Mercedes fuel filters and needs to have the hole plugged as part of the conversion process.

There is a huge picture at the top of this discussion of a banjo bolt.

 

If you cannot see it you may have to reset your borwser.

Please don't ask how...I don't know.

The image is actually on the biodiesel.infopop forum.  You will certainly have to be logged in to infopop to view it.  Even after doing that I couldn't view it in this forum.

I saved the picture and attached it here, hopefully this will work.

It looks like the bolt has already had the modification, then was filed nice and flat.  Is that correct?

Also, to be absolutely clear, we are talking about the return line banjo bolt, right?
