am i ok for iva to run fuel hose not copper pipe down trans tunnel all clipped and right markings on hose .running on bike carbs.

Yeah, but i don't know why you would want to.

Don't do it Use hard line if you can't see it.

^^^ 8mm micro-bore heating pipe is one possibility. The petrol hose tends to go hard/crack and quite a few have had issues with leaks difficult to fix/spot transmission tunnel...
