Joe Shmo 157 #1 Posted May 24 I have a rebuild kit for the metal bodied fuel pump and when installing the diaphragm, does the arm go in and turn or does it just go straight in? Share this post Link to post Share on other sites

Mike'sHorseBarn 2,998 #5 Posted May 24 I have had to file some away from center area where it twists to make the new diaphragms fit. Not every pump, but some so if it goes hard, don't force it. 2 1 Share this post Link to post Share on other sites
peter lena 8,608 #6 Posted May 24 @Joe Shmo super lube , silicone based ,oil is made for dissimilar connections , make s rubber / metal fitting very easy , also EXCELLENT CHOKE / THROTTLE CABLE LUBRICANT , check out the temp range , make it drip out the entire length , local H/W store $ 6 also great for fuel tank valve replacement . pete 1 Share this post Link to post Share on other sites

953 nut 55,187 #8 Posted May 24 One more point, the diaphragm should be stretched (move the lever full stroke) before you tighten the screws or the diaphragm could rip. 2 1 Share this post Link to post Share on other sites
