C&W 77 #1 Posted May 5, 2020 Anybody got a picture of a correct fuel pump for a k161 Took my engine apart the fuel pump that is on it has a straight curved upped shaft It does not ride on the lobe of the cam I don't have another engine to pull one from to see what's going on. I wonder if this is the reason why the tractor I have was just set out to rust away ,no way it ever pumped anything lol I'm figuring there is a offset type shaft for them maybe I will be able to heat it up and bend it Thanks for any help Share this post Link to post Share on other sites
ebinmaine 72,674 #2 Posted May 6, 2020 If that's the original engine I'm thinking there's no contact on the cam. That's a vacuum pulse type pump. No arm needed..... 1 Share this post Link to post Share on other sites
C&W 77 #3 Posted May 6, 2020 Well that would make since I'm thinking it was replaced fuel pump. I looked at another 8hp engine I saw it was missing the arm thought it was a part salvaged pump so looking at what you say it is in fact a pulse pump never knew they exsisted thanks for the info 3 Share this post Link to post Share on other sites

Racinbob 11,929 #5 Posted May 6, 2020 I learned about the pulse (vacuum?) fuel pump a few years ago when I was working on an 854 for a friend. I pulled the leaking pump and gadzooks!!!! there's no arm. The guys here set me straight and a new diaphragm from Brian and I was good to go. I'd be interested to see if a fuel pump body off a K341 could be converted into a pulse and used on a K161 I have. 1 Share this post Link to post Share on other sites
C&W 77 #6 Posted May 6, 2020 Yeah I looked at the one and thought they was just plugging the hole with a defected pump lol and the other motor they where just hoping the arm would move to pump some gas haha 1 Share this post Link to post Share on other sites
