Biodiesel is a stronger solvent than standard mineral
diesel and so
all the accumulated gunge in the tank and pipes from years
of driving
dissolves into the new fuel. When the biodiesel is pumped
through to
the fuel filter these particles are deposited potentially
blocking the
filter. Shortly after starting to use biodiesel it is
usually
necessary to replace the fuel filter at least once. After
that the
pipes and tank are clean and fuel filters will only need
replacing at
standard service intervals and you will have a much
cleaner car.
Biodiesel's solvent powers also make it hard on any old
style rubber
piping. All rubber piping and other rubber parts in
contact with fuel
should be immediately replaced with modern hard-wearing
long life
nylon pipes to prevent problems. Most modern cars no
longer have true
rubber parts and so this may not be an issue.

I have recently produced my first batch of Biodiesel and
intend
running my ageing Volvo 940 on this fuel also I intend to
power my
2002 2liter for Transit on the same.

Can anyone out there in Cyberspace tell me what rubber
seals and pipes
will need changing because of the cleaning solvent power
effects of
this fuel.

Basically, if you can get to Teflon or a high grade if
viton, you'll be in good shape for the seals. Also, if
there are any yellow metals around the fuel (copper, brass,
etc), or mild steel, the biodiesel will eat them nicely.

You can look up chemical compatibility with biodiesel.
There are a number of sites which give the charts. Google
will get you there.

Remember also that the cloud point of biodiesel is about 50
to 55F. If you allow the fuel to drop below that point (or
even approach it), you may be sitting still for a long time.
