I have a 1991 Mercruiser 4.3 2 Barrel inboard. I replaced the fuel line between the fuel pump in the gas tank and added a fuel water separator my question is I used 3/8 hose from AutoZone that is fuel injected rated so it's more dense than the carbureted stuff do you think it will be a problem? Is it going to collapse? Is it a fire hazard? Or am I just overthinking it?
