So long story short the fuel line popped off one of the carbies while i was on the road tonight and sprayed petrol over everything. No fire and everything seems to have survived, panic subsiding. So my issue is that the small brass tube that the fuel line clamps to on the carb has come loose from it's housing. It was still held in the fuel line by the small hose clamp. I pushed it back in and it seems to have seated alright but i'm quite concerned that it will fall out again. Is there anyway of fixing that brass tube in there? Should i try to pinch it in there with a gentle tap or maybe some sort of glue? Any help would be greatly appreciated.
