Volvo vnl 2020 d13

Truck died on me on Friday night, due to low fuel pressure. There was a leak from under the filter housing, when I tried to prime system. Had to be towed to the dealer. After replacing the housing they found that the fuel pump had to be replaced as well. Picked up the truck today and the same problem happened. There is a leak from under the housing. Drove only 200 miles. It seems like the problem is somewhere else, any ideas ?

The same codes as previously:

16 dtc p008a00

16 dtf p008700

 

Being honest not - don’t have any pictures
Today I got it fixed, but not positive for how long it would last.
That’s dealers comment
“Found fuel leaking from primer pump button. Removed screws and primer top. Found internal pump to be loose and not secured into place. Tabs on internal piece are bent outward. Installed new primer. Truck ready for service”

 

So you think there couldn’t be such condition, when the fuel pressure suddenly grows too high, so it could damage what I mentioned above?
I really appreciate your help, drove around 200 miles so far. Will let you know if smth happens again.

 

Nothing is wrong now, but it never been wrong before. Nothing was leaking until just suddenly truck just stops running. I’ll keep you updated

 

Couple days and no problems since. Do you think I can blame mechanics at first place? Since they replaced the filter housing and missed the problem with the primer pump or I just not fully installed it into place.
