Re: 3/8 fuel line

I run 3/8" which is -6 on my blower motor from the gas tank all the way to the carb on my 500 HP blower motor. That will flow enough fuek for your engine. You should only go from bigger to smaller line not the other way around for good fuel flow.

Re: 3/8 fuel line

My engine is supposed to be making over 600 hp, and i'm trying to find out why it's not running like it should. I know my converter has some to do with it.
