Anyone know how much fuel pressure the lift pump on a case 580E should put out? I was thinking of putting a pressure gauge after the fuel filters before the high pressure pump. I just wanted to monitor the pressure to make sure enough pressure was getting to the high pressure pump. you know how sometimes fuel get contaminated and starts clogging the fuel filters i just wanted to monitor the pressure just to make sure my filters are not getting to clogged between changes. just tring to be proactive and a little careful.
