475 C 15 acert twin turbo.(2005)
Runs rough after fueling up, most of the time. Its not bad fuel as it does it at any fuel up location. Its not the filters, as it does it with brand new ones. Its not the difference in fuel temp
between new (cold)fuel and whats already in truck tanks(hot). If it sits overnight after fuel up, fuel temp equalized, it still does it in the morning. Tried keeping truck running or shutting it off while fueling, still the same result. Roughness is mostly at idle and low rpm and will gradually go away while driving, could be after half an hour or two hours, differs. Just had a platinum Cat inframe done
(not related to this issue) and still does it. Any ideas ? Fuel pump ? Fuel pressure? Read a lot about an updated spring in the pump.

I have seen the check valve in the fuel filter housing go bad, or have debris in it causing the fuel to leak back. best thing to do is put a gauge on it, and check the pressure to see how much pressure you have, and once you shut it off, see if the pressure is maintained at the gauge or if it drops off.
