i decided to clean the carbs on my nc today as i had to get recovered home last night by a very nice rac man,

anyway to cut a long story short ive cleaned most of the internals and checked the float hights and stuff but after finishing, i noticed that where the pipes from the sub-airfilter join the carbs the rubber seals have perished and snapped.

i just wanted to know does anyone have any advice to help me out, or do i have to pull all 4 carbs apart form each other and fit new seals?
