My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made. No rate, site gets it all.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

You have a fuel problem or a check valve problem where the fuel is draining back to the tanks and you are losing prime.

I would have the fuel system gone through and see if there is any air getting in through one of the filter o-rings, a cracked heat exchanger on the ECM, a bad check vavle on the heat exchanger on the ECM, or a bad check valve in the filter housing causing the drain back.

You'll find it on the low pressure side which is before the high pressure pump. Trust me if it was on that side, you would know it for fuel would be going everywhere and cutting a whole in the hood for it is at 22,000 psi at idle after it. So the issue will be before the pump on one of the 2 check valves.

__________________________________________________________________________________________________________________________

You want a 5 star service and I want to provide a 5 star service. Please consider that I don't know your skill level as well as I can't see,

touch, smell, hear the vehicle/machine in question. Please provide as much detail as possible and I will provide as much back.

Once an answer is provided, you should see a rating screen. Please rate my personal service to you. The ratings are my personal feedback,

they are not the site feedback.

Thank you for allowing me to assist you through Just Answer!
