formariz 12,040 #1 Posted March 10, 2009 Removed fuel pump on a spare k-161 for inspection and cleaning and noticed that it does not have the mechanical lever I see in all diagrams and photos of this type pump. Is this one perhaps vacuum operated or has the lever fallen into engine? Cas Share this post Link to post Share on other sites
BadDad 1 #2 Posted March 10, 2009 Man that sounds familiar. When I was doing my 855 with a K181s all of the pictures had that laver on it. The 1st thing I though was it fell off. But I made some calls & found that I had what they call a pulse vacuum pump. I was still not able to find the rebuild kit for it, luckily I was able to clean mine with carburetor cleaner & get it to work. I do hope yours is like mine, & I hope you are able to fine a kit to rebuild yours. Good luck Share this post Link to post Share on other sites
formariz 12,040 #3 Posted March 11, 2009 Thanks Donnie I hope that is what I have. I just can't find any literature referring to that type of pump.I am tempted to remove the oil pan to see if it is there. Share this post Link to post Share on other sites
BadDad 1 #4 Posted March 11, 2009 Well Cas I know these people helped me a lot: Manufactures Supply, 1-800-825-8563 http://www.mfgsupply.com I called them gave them the model number, & the spec number with that they even sent me a fax diagram of my fuel pump. Before you take it apart you might give them a call. I do hope this helps you out. Donnie Share this post Link to post Share on other sites
Horse'n Around 22 #5 Posted March 13, 2009 Cas, I ran into the same thing on the K161 that is on my 702 last week. Mine has a vacuum fuel pump.It had me scratching my head for a second till I noticed that there was no place on or in the housing for a mechanical arm to piviot on to begin with and also the diaphram (sp?) has no metal in the center of it for the lever to contact. I can only assume that if the pump was mechanical the diaphram would have metal where the lever would contact it so it wouldnt put a hole thru it.The diaphram was caked with nasty old varnish and disks(valves) were stuck tight closed so I cleaned the whole thing really good and put it all back together and it is working like a champ. Boy Im happy about it too, when I saw how much a pump costs I nearly passed out! John Share this post Link to post Share on other sites
