Biodiesel and my ageing Volvo 940

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.
