I've watched people struggle to get the fuel hose into the tank before , the correct way is to cut the hose much longer than it needs to be or use a full length and cut the end of the hose on an angle before pushing it into the hole , then once the hose is in cut the end straight again and put the filter in the end of the hose from the fuel cap end ,then pull the hose so the filter is back in the tank and cut the hose to the correct length to fit the carby fuel pipe fitting.
