Part of fuel return. Mine has a hole on the bottom. No idea if its supposed to or if its broke. Only 2 references I can find call it a duct collector so I assume miss translation and dust collector but no references... https://ibb.co/K6tG7Sz https://ibb.co/2kcVcV1 Edit: Called and emailed g&r Joe hasn't gotten back to me but it was also an end of day call so I told him to get back to me tomorrow.
