Bit of a 50/50 one here!!, i've removed the std recircs, and want to fit a Samco hose directly onto the lower intake pipe, (bore size is 34mm), now Samco unfortunately only do a 35mm or 32mm hose.... will the 35mm be ok with just a tight jubilee clip or should I get the 32mm Samco and squeeze it onto the 34mm pipe? , that's if it fits!!)

35mm with a good jubilee clip will be fine.
