of the fuel pump.
Dry type filter elements (paper filter) are not
permitted as they could absorb water and thus reducing flowrate. >>
Then I have been badly served, as my installation manual is dated Sept.89 ,
(for an engine delivered in 95) and there has been no update. It gives the
mesh size as 0.3mm and does not mention paper filters. And Rotax don't mention
car filters.
All this is entirely academic as the experiments I carried out verified that
the car filters I have used do not have a water problem, whatever the material
may be. This is a positive contribution to what has caused serious situations
for some of us and should be treated accordingly.
