got the motors out this afternoon and had a little trouble starting the merc 9.8 so i pulled off the cowl and after it started with a few more pulls it managed to stay running but was belching fuel out of the carb intermitantly and also seems to have a tear or punture at the top of this fuel line i have circled in the picture attachment . is this a simple fix like just replacing this hose ? , or is it unscrewing the fittings and getting new ones etc.?? any advice /help is going to be appreciated . thank you in advance.
