haykarenhardy Posted August 17, 2008 Posted August 17, 2008 The fuel transfer pump on my 7790 is loosing prime, have to manually prime the tractor for a quick start up. I have replaced all the low pressure fuel lines and cleaned the screen in the transfer pump. Should I order a mechanical fuel pump from Lombardini - Kohler or buy an electric pump like some of the members use on there 7790's. If I go with a after market electric pump should it provide more than 2-4 psi? Will an electric fuel pump work OK with the thermal start? Stan
