[QUOTE="96dreamer, post: 16814820, member: 52560"] I got the fuel system buttoned up last April 2021 but I couldn't tell you how much it was actually driven on hot days. My son was born in July so I don't think it got driven much before or after then. I would have to go back and see if I have any logs over that time. I am pretty sure that earlier this summer when i first had the issue and it was 99 ambient with 90% humidity was the hottest day I have driven it with the new fuel system. I know there are quite a few guys running the pumps/filters in the same location as me and either they are not having issues or i was not able to find posts where they were. The only thing I can think would be a flaw in the system was where I had the return line running originally. It was dumping directly into the sump pickup area. My initial reasoning behind this was to prevent starvation in low fuel situations but fuel heating/aeration/cavitation hadn't crossed my mind. Since I started having issues I moved the return to the driver side of the tank pointed away from the pickup. However I am afraid having it there caused damage to the pump that is now giving me issues. [/QUOTE]
