I need this classic corvette fpr for ls3 engine:

This fpr have feed 3/8" but my fuel lines is 5/16". I need quick disconnect from 3/8" to 5/16", like this:


New design from russell is interesting because have retainer bolt instead plastic clip which is I think much safer. But here is no fitting for 5/16" hose.


What clean solution I have without using 5000000 adapters from-to?

thanks
