In the US we have similar filters to this and looking on line I am particularly
unimpressed with filters with just a straight nipple end. Although easier,
inexpensive
and used by the auto industry with their new fuel clip seals, the ASTM
crowd in LSAs went to them but use common fuel line. I will stick to a metal
hose barbed end filter and continue on as I am.
You as the manufacturer of the aircraft can make those choices if your country
regulations and inspectors allow it.
A few years ago, a local A&P broke a similar plastic filter on an LSA by
clamping
down the hose too hard. This plane had a hose replacement using fuel injection
hose, and being a hard hose, he clamped the crap out of it until it cracked.
He called me over to his shop and we had a talk about it, and with carb hose and
less pressure it seemed to hold just fine. The filter only costs a couple
of bucks but it was back to the store to get another. I think the plane was a
German LSA.

Hi Bud,
You have certainly developed some good coping/management techniques with the
screw
together filters BUT have you looked at the Hengst ones I have recommended?
Don't know about the USA but here in Australia, filter choice is not usually
seen as an something the aircraft maker has the last word on (they are a
consumable
like oil or coolant choice). Further the Hengst filters are quite popular
in LSA class aircraft operated in Europe. Soooo much simpler to use than the
screw together type.
