The other school claims that there were two types of pump manufacturered for this car: the one made in the USA and the one made in Europe.

Apparently, the European manufacturers had the foresight to incorporate poly seals that don't break down in the presence of a powerful solvent. The USA manufacturers, however, used much more rubber in their blend.

Can anyone shed some light on this? How would one identify their pump?

Thanks,
