richmondred01 2,307 #1 Posted November 30, 2019 Going to install FACET POSI-FLO FUEL PUMP Im tossed up as to which one the 1-2PSI or 1.5-4PSI. I’ve used the 1-2 psi in Kohlers with good success. However, the onan is a different animal. What do you guys use? thanks. Share this post Link to post Share on other sites
Kurt-NEPA 755 #2 Posted November 30, 2019 I've been using an Airtex E8016S electric fuel pump on both of my 520H's. They have been flawless. They are 2.5 - 4.5 psi pumps. I'm not sure I need that much pressure. Hope that information helps. Share this post Link to post Share on other sites
WildmanC120 613 #3 Posted December 1, 2019 I'm using a Holley look alike version of the facet on my P216. I don't remember the pressure. It's been fine for a few hours now. Just make sure you remove the manual pump as to not pump fuel into the crankcase. Share this post Link to post Share on other sites
