 Typical I do not know, smart I think.  You leave a big enough access hole in
the stub wing web to get a wrench in to disconnect the pipe and through the
same hole you slip in a deep socket and out she comes.
 
 Having said that I pulled mine once  and found nothing significant.  I also
have a 2 micron mesh filter before the boost pump which I located under the
right hand seat.  It is an Air Flow Performance pump and filter combined, also
has a bypass.  This filter picked up some very fine crud after the first 25
hours, only a trace since then (280 hours).  I also have an Andair gascolator
on the engine side of the firewall but it is always clean.  We have to have a
gascolator in Canada, must say something about our national psyche!
 
 Before closing the tanks, I blew them out, vacuumed them and then wiped them
with a painter's tack cloth.  All my piping was blown out with air and it is
all 3/8" Al tubing, no plastic.
