Decided to change Diesel Filter the other day. not starting easily after that particularly after a few hours standing, had to prime the filter and then started fine. even though car is only about 7 years old fuel hoses have gone hard and wire clamp not able to provide tight seal. replaced main fuel line to filter and changed to better clamps , no more issues. important to connect main fuel hose to diesel pump last prime and hold your thumb over end part to prevent air sucking back into filter. as you squeeze bulb push onto diesel pump and all air should be expelled. i believe this could be a common problem and worth checking any fuel lines on Patrol older than 5 years
