140HP and up should use 3/8" fuel line.

Adequate hose size is required for running. But would have no effect on priming or starting.

Be sure the hose fittings are replaced with 3/8" sized ones, too.

That is exactly why i replaced lines with 5/16,that was the size that fit the fitting on the built in gas tank 3/8 seemed to fit a little loose
