I have been following the fuel filter thread with interest. Having run a
PA28 for a good many years and NEVER having a fuel problem, except for a VERY
occasional drop of water - which is easily disposed of pre flight by the drain
valves. I am inclined to think that the problems of grot in the filters
arises entirely from an accumulation of matter caused by interaction between
the
fuel and the tank material. It seems to me that this is something that the
manufacturers' boffins could easily remedy.
I have had to clean out carbs to get rid of ' snot' which I have never seen
on any other aircraft.
The point made yesterday, that in keeping the filters easily accessible, is
also valid. It is essential , in my view, that this is the case so that both
pre flight and inflight inspections can be made. The filters in my 914 are
parallel, with the pumps and very easily disconnected and cleaned out. I
have never found any grot in there but will continue to do this at regular
intervals.
Another view, expressed by someone who has far more technical and general
Europa experience than I, is that both pumps should be on all the time.
Comments appreciated.
