Davedownunder Posted January 25, 2015 Share Posted January 25, 2015 My E7 Valueliner has this issue that it wont start in the morning (or after about a 6 hour rest) without the fuel being primed up. Once the truck is going throughout my work day, it will restart OK. I have been living with this problem for a few months now and have tried many things to overcome this issue. Initially suspecting there is "air in the system" I have replaced practically all fittings and hoses to eliminate any intake of air. All hoses have been replaced All fittings have been replaced The pressure relief valve has been replaced The Primary Filter head has been replaced. When I removed the old one I did find 3 fractures in the threads and was excited that this might be the answer - however it proved not to be so and the problem remains.A new fuel pump has been fitted - Another suspicious clue is that there appears to be excessive vaporization in the fuel tank. this excessive vapour will be present as soon as the fuel starts returning to the tank from the engine. How much vapour is normal? Is this a related problem to my fuel for starting issue?I have noticed that the suction line from the tank to the Primary filter is empty and even the Primary filter having about an inch at the top empty on inspection after a period of a few hours. The lines from this filter to the lift pump and then subsequently to the next filter on to the fuel pump are full. Any Clues DAVE Quote Link to comment Share on other sites More sharing options...
