Kagnew66 15 #1 Posted April 29, 2018 Please help me, I'm failing... I have a 701, but I have a feeling this question is generic. What do you ask for when you're looking for a gas tank nipple, or a Carter N fuel inlet fitting, or a fuel pump tube and fitting. I could add - a drain plug for a 5025 transmission? These pipe thread designations are mind boggling. I can probably forget metric for the old stuff, but maybe there is a correlation. Has anyone got a list? I want to help this old gentleman to get back on his feet. Thanks a lot. Share this post Link to post Share on other sites
squonk 38,928 #2 Posted April 29, 2018 I believe the tank is 1/8" pipe thread. Carb and fuel pump are 1/8" pipe to 3/16" compression and the steel tube is 3/16". Trans drain plug is 1/4" pipe. 1 Share this post Link to post Share on other sites
