I was having issues with my 2011 Odyssey dying and finally not starting so I replaced the fuel pump assembly(with a cheap one). Problem immediately resolved for a few weeks but then it seemed that the assembly started to fail because it would sputter when in reverse and would sometimes die when coming to a stop at a light. It was also loud. I replaced it with another one(still cheap at $60) which seemed to be better. Drove fine going forward but still hesitated when in reverse or on a slight incline and still loud. Finally I figured I would just buy a premium part and purchased a Delphi FG1185($200). It was listed on Rock Auto as a premium part that was supposed to be very quiet. Once installed it was still very loud and the van still hesitated in reverse(not as bad but it shouldn't at all). So to me it seems that the diagnoses of the the fuel pump assembly is still correct but that maybe there is something I am missing. There doesn't seem to be a fuel filter but maybe I am wrong. Any suggestions on what the issue may be? Do I need to get a different assembly? Another part? Any thoughts or suggestions?

and replace your torn intake tube...
Yes. The original fuel pump is probably fine, so I hope it was saved. On these cars, the fuel pumps hardly ever fail.
The torn intake boot is a particular problem on these cars due to the VCM. If you search on here for those words, you'll find more info.
Just some weird things on these cars that can be easily mis-diagnosed by people not familiar with them.
And some more info in this case - shifting to reverse should have no difference regarding fuel delivery. But it will torque the engine the opposite way, which will allow greater motion due to the engine mounts having failed after a lifetime of abuse suffering with the VCM system rough running, and that will open the crack in the cracked intake tube, allowing unmetered air into the engine, causing misfires, rough running, and perhaps engine stop.
