I have a Carter super pump with the 1/4 NPT. I tried to use the Edelbrock/Russel flexible line. The hose end was huge! Then came the fine print... ugh! What a pain!
A Fragnola 90* fitting came into play. It screwed into the Carter pump. I took the big end off of the Russel fitting which allowed me to use the rest of the line directly to the Fragnola fitting.
