50 merc fuel lines

Running new fuel lines on the merc. Does anyone know what the standard size is for fuel line. Im gonna run it in stainless from the tank to the motor ? Shes almost on the road !! Check out myspace for before and after pics........... look up 50merc !! Thanks fellas

 

i like to use 3/8" for fuel lines , and usually just with steel lines..just my opinion , but i don't see a need for stainless

i also like a filter right out of the tank , then an electric fuel pump that's switched to run only when you want it to. makes it easier to get it started after the car sits for a while. make sure the rear fuel filter can be accessed from below.

 

Thanks for the info !!
