carlosking450 149 #1 Posted October 14, 2023 Hello everyone, the 12v universal fuel pump on my Wheel Horse 702 is broken, I want to buy another one but I don't remember the PSI of the old one, what PSI should the pump have for my 7hp Kholer? Thank you 1 Share this post Link to post Share on other sites
Ed Kennell 35,857 #2 Posted October 14, 2023 2.5 to 4 PSI will work. 3 Share this post Link to post Share on other sites

davem1111 1,932 #4 Posted October 14, 2023 I've had good results with the Carbole pumps on 2 of my tractors. I believe they have a PSI limiter and a check valve to stop backward flow. 2 1 Share this post Link to post Share on other sites
carlosking450 149 #5 Posted October 22, 2023 Thank you all, I received my electric pump, I assembled it and everything works correctly, although I am interested in installing your original pump! 1 Share this post Link to post Share on other sites
carlosking450 149 #6 Posted October 28, 2023 Hello again, I have looked at photos of other Wheel Horses and I noticed this fuel pump, could it be fitted to any engine? What do they need for it to work? Thanks again, greetings from Spain! 1 Share this post Link to post Share on other sites

953 nut 51,795 #9 Posted October 29, 2023 That is a vacuum operated fuel pump which would be connected to the engine block and be operated by the change in pressure in the crankcase. Onans and lots of other engines use them. 1 Share this post Link to post Share on other sites
carlosking450 149 #10 Posted October 29, 2023 On my Kohler K161, it covers the original pump housing. If I put a connection on that cover, could I install a vacuum pump? 1 Share this post Link to post Share on other sites
