Recommendations for a stainless steel flaring tool

I will be replacing my main fuel line with 3/8s stainless. I am running 4 link in back, which rules out buying pre-bent line.

I am looking for recommendations on flaring tool with the following requirements; double flare on stainless steel. I've only done a few soft metal test flares, so ease of use is a plus. And of course quality of flare is worth it's weight

thanks for the help and education
