SPINJIM 1,978 #1 Posted November 23, 2016 My 417 with the KT17 series II engine is not getting fuel if it is not run for a couple of weeks, so I bought an electric fuel pump. I've read most of the threads on installing it, but I don't know whether to remove the old mechanical fuel pump, or just leave it inline to serve as a check valve. If I remove it, I guess there are cover plates to cover the hole, or I could just leave it on the block, and bypass it with the fuel line. The old fuel pump is a bear to get at, especially in a cold, unheated workshop with cold fingers. The 417 is my snowblower tractor, so I have to do it now. Thanks for any advice, Jim Share this post Link to post Share on other sites
Achto 26,547 #2 Posted November 23, 2016 I would leave the old pump bolted to the block and just bypass it. You can always remove the old pump and install a cover plate later after it gets warm out if you wish. 3 Share this post Link to post Share on other sites

953 nut 51,646 #4 Posted November 23, 2016 did that on my GT-14, it is a bear to get too so I just cut the hoses, plugged them with 1/4" dowel and bypassed it. Be sure to install a fuse on the line that feeds it. 1 Share this post Link to post Share on other sites
Kurt-NEPA 755 #5 Posted November 23, 2016 Another vote for leaving the pump in place and bypassing it. That's what I did on both of my 520H. BTW, I have no regrets. Mine both fire up on the first or second revolution. That wasn't the case before. Kurt 1 Share this post Link to post Share on other sites
BESTDOGEVER 218 #6 Posted November 23, 2016 Yup a short piece of hose from inlet to outlet will keep stuff out and prevent any vacuum leaks then you can forget it. 1 Share this post Link to post Share on other sites
SPINJIM 1,978 #7 Posted November 23, 2016 Thanks everyone for the help. I'll take the advice, and just bypass the old pump for now. Good idea to just turn the outlet hose back on itself to the inlet. I just ordered the cover for the hole in the block, but it won't be going on until springtime. If I take all of the covers off of the engine now to get to the pump, it will surely cause a snow storm, and I won't have a working snow thrower to handle it. Happy Thanksgiving, Jim 3 Share this post Link to post Share on other sites
