My C182G is having an "odd" issue that can't be recreated every flight. On x/c flights I do the old "right tank, then both, then right tank" to manage the uneven C182 burn that the plane is known for. However on 1 out of 5 flights, it appears that the fuel flow will gradually decrease while the selector is on R. I have a JPI 450 and in level flight, cruising on both, the flow will be ~15 GPH. But going to R it will stay ~15 until it will slowing start dropping... At 12 GPH, the engine will start getting cranky. Going back to BOTH, the fuel flow will spike, you can hear the engine recover, then settle back down to ~15. In testing, I also tried flipping to L tank and encountered the same issue; fuel flow slowing started decreasing. Back to both, and it stabilizes - no issue.
Any idea what could be the cause? Perhaps the o-rings are going bad, and causing a block on each selector? I've read a good test would be to idle the engine at 1,000 RPM and set the fuel selector to OFF and see what happens.
Tried doing a search, but it seems like most everything for C182 is around uneven fuel burn.
Thanks for any input.
