I need to know the size of the inverted flare nut on the 455's fuel pump
discharge. I'm pretty sure that it's 5/8-18, but I'd rather not pull my
fuel line off to find out.

Patrick - I am using an electric fuel pump with my TBI but I had the
old fuel pump in my garage. It definitely is a 18 tpi and the
threads measure 6.20 outside of the thread points so it definitely
appears to be a 5/8".
