Posted July 17, 200915 yr comment_289777 I called Bruce today and asked this question, but made the mistake of not writing it down and forgot. Seems like he said 1 3/4", but I wanna be sure before I go cut that size hole in my new air cleaners. Also, will regular 1/4" fuel line fit the fuel bowl vent outlet nipples on top of the bowls? Thanks! Edited July 17, 200915 yr by g9m3c Link to comment https://www.classiczcars.com/forums/topic/32558-3-screw-sus-inlet-throat-diameter/ Share on other sites More sharing options...
July 17, 200915 yr comment_289780 They are actually 46mm, but 1 3/4" is really close. Link to comment https://www.classiczcars.com/forums/topic/32558-3-screw-sus-inlet-throat-diameter/#findComment-289780 Share on other sites More sharing options...
July 17, 200915 yr Author comment_289782 Thanks for clarifying that! 46mm converts to 1.811 inches, ao I'll probably cut them to 1 13/16" just to be safe. Any idea on the float bowl vent outlet size?
