Man In Black 3 #1 Posted November 22, 2020 Can anybody tell me what psi inline fuel pump will work with my 8hp old cast iron Koehler engine ( Year 1978 ) ? The lowest psi pump that I can find is a 2.5 - 4 psi . Is that too High ? Share this post Link to post Share on other sites
pfrederi 17,961 #2 Posted November 22, 2020 (edited) I run 1.5 -4 on several Kohlers. Some people would prefer a lower PSI there is 1-2 psi version of the Facet posiflo made in USA i have had good service from all of them. I did not have good luck with Chicom versions....
