Re: Gas Line, 3/8ths or 5/16ths
Dave,
I replaced mine on my 85hp last season. I could not get 5/16 so I had to go with 3/8. I made it work but the black plastic inlet on the engine would rather have a 5/16. I had to crank down on the clamp more than I like to make a tight seal.
The original that came with my engine was 5/16.
Regards,
John
