Graham,
I did not. You wrote

That was my point only.
If you change a filter let is say 5 to 10 times during rubber hoses life time,
they do not get eroded at all.
That is surely The Fact.
> It is possible to block the filter in one tank filling
That is of course true. I know it because I have been there.
But NEVER again. Why?
Because I am now a better pilot and
1) my tank is totally clean since that incidense.
2) there will never ever be any contaminants any more in my tank becauce
a) I use only carefully filtered (by me) unleaded autopetrol (Mogas)
b) I use only totally clean 100LL which is a self-evident truth (at least in
Finland)
When refueling our planes we have to be very carefull !
For example it (Andair) does not help if we refuel JetA1...I mean it doesnt make
wonders.
I think Europas idea to use two parallel installed inline filters is good.
One for main and one for a reserve tank. It is reasonable.
And - BTW - those in-line filters are also checkable before EVERY flight.
I do it every 5 flight hours (like removing the upper cowling same time also).
Nice to change ideas with you, Graham.

PS: should I take a photo from Rotax Original -type in-line filter?

means nothing for quality rubber hoses.
