Sounds about right. I struggle to get my pvc hose over the MBC, think it's 3.2mm ID so you have to stretch it for ages before it'll go on, then if you arent quick it tightens around a barb and has to come off again 
Should probably pick up some 4mm stuff actually and redo my MBC line, it's oiled up to f*ck and I'm not sure if it actually works at the mo
