The Filter King is still made by MALPASSI
Malpassi was Chef Engeneer of Del Orto
when he developed the Filter King after WWII.

is used religiously because it has the ability
to regulate and filter fuel without restriction.
It is available in two different sizes,
with a glass or aluminium bowl.

They also are often sold by Motorboat / Marine supplyers.
