Craig,
I am running optimax in my race car at the moment. I have new rubber fuel
lines running the whole length of the car and have had no problems as yet.
As you have said I may have synthetic rubber. I am conscious as to what can
happen to rubber when it has the wrong solvents run through them.
Regards
Trev

Subject: Optimax eating rubber fuel lines
Because of the elimination of lead from fuels, the oil companys have to
use a substitute. Aromatics such as benzol, toluene, xylene are used as
a replacement. Aromatic fuel blends act as a solvent with rubber parts
and require the use of synthetic rubber for fuel hose. Therefore if you
wish to run Optimax or Unleaded it is necessary to use synthetic-rubber
fuel lines and replace any rubber seals in fuel pumps or carbies etc
likely to cause problems.
I have heard recently of people having problems running Optimax. Just
this weekend at a rally I was helping with servicing. One of the cars
was running Optimax with old lines developed a fuel blockage in a 45mm
Weber. Didn't think of it at the time but i'll have to mention it to the
owner as a possible cause.
I learnt a lot of this information from an Aerospace book written in
1963 talking about fuels used in World War II so it aint new!
Craig.
