Вспененная медь.
А можно натолкать синтепона в бак и в него засунуть заборный шланх вообще без искателя…
На бочке может двигатель встать.
Чтоб не заказывать и не ждать , иду в запчасти для бензо- прибамбасов и беру фильтр для бензопил и тримеров, замечательно работает.
Только бачек с собой надо для примерки по горловине , а то размерчиков всяких полно…
А можно бак из изделия N 2 изготовить. Мягкий такой, и дренаж не нужен.
Срок службы такого бака - 15 минут, после чего изделие теряет герметичность.
Как вариант- пакет от кетчупа или лавсановый пакет от кофе- продержаться дольше.
