I have a 10.5HP on a Cox XL Scout and am wondering about the brass fuel inlet at the carburetor. It is very short and doesn't have much of a barb and no matter how tight I try to get a worm drive clamp it sooner or later vibrates off. I am wondering if it is possible to replace the part, how to go about it and can I get a right angle one instead of the straight one, which takes the fuel line right across the top of the muffler.
