Not at present. I ordered Daerr's

Another idea is to use separate
filler necks, like it is usual for
the water tanks which are on same
place and of same design. To get the
fuel into the main tank you only
need to have a regular fuel hose
which is connected to the return
line of the original installation.

I don't know about these, but there
are water tanks made of PVC which will
resist Diesel. But they are not certified
to carry fuel at all.
