I recently purchased a Kamoer x1 dosing pump and made a homemade dosing container with a standard 1/4 in bulkhead. Now that I’ve opened the pump, I’ve realized the tubing that comes with the dosing pump is too small for the bulkhead (it came with 4mm tubing) and it won’t seal/prime. Is there an adapter where I could just buy some 1/4 airline tubing to then connect to the bulkhead? (I’ve searched till I’m dizzy and can’t find anything). Thanks I’m adjacent!
