HELP - LSx in Jetboat, low fuel pressure fault
Hi Guys,
Im hoping someone can help me?
LSx in a jetboat - see https://xtremejetbayofislands.co.nz/
Been running perfectly for 300hours
suddenly, no warning, low fuel pressure fault... (installed a manual gauge verified sender is good)
pressure is steady 59psi up to 4000rpm can run all day like that...
anything over that and the fuel pressure starts dropping off
I have removed all the fuel lines, inspected, cleaned.
Changed the fuel tank pickup.
Changed the lift pump, filters, high pressure pump
and tried 2 different branded pressure regulator/filters
Our season is upon us and i need some guidance
any suggestions most appreciated, Thanks!!
