Could an improper seal on my fuel suction assembly be causing these issues?

Long story short[ish], my fuel sender gauge went bad on my 2007 Yaris and on Monday I ended up having a mechanic go into my tank to replace what everyone assumed was a bad fuel pump only to discover that it was actually just out of gas. After getting everything back together and pouring in 5 gallons, I was able to drive it about 15 miles over the course of two days before I noticed it was getting a little sluggish the check engine light came on.

On Wednesday, I run into a store, and when I come back out the car starts very roughly, engine is shaking a bit. I'm thinking maybe it will work itself out once I get going, but as soon as I pull out of the parking spot the engine dies on me and I coast into another space. I can't get it to start. I have about 25 miles on it since Monday, so there is no way I am out again. I hit up the mechanic and he asks me to add more gas to see what happens. I come back about 3 hours later and dump in another 5 gallons, and it starts on the second try. It's rough, but I am able to get it home.

It sits until Friday when the Mechanic comes back over. He puts his scanner on it and reads out a few codes and starts going through them to figure it out. He starts by cleaning the MAF sensor, and the car starts up wonderfully. We go for a ride through the neighborhood and everything seems peachy, better than ever. We hop on the free way so we can test it at higher speeds, everything seems good, though when I hit around 70mph, which is about 10 miles into our drive, I feel the acceleration cut out on me for a moment. The mechanic can't really feel it like I do so he assumes it's just the gears shifting or me hauling it or something. Anyway, we exit and I am going around 45mph and the acceleration cuts out again, only this time it is very obvious since I have the pedal to the floor and nothing is happening. He thinks maybe I am low on transmission fluid, so we get it home and check that out. Levels are fine (though it is probably due for a change). While he is checking it, the car is in idle and the engine starts developing a shake and the exhaust is popping a little. His scanner is reading misfires. He unhooks the fuel line to check the pressure and he says it is flowing but he expects it to shoot out like a super soaker (I guess he doesn't have a gauge?), so his next assumption is that maybe he kicked up some gunk on Monday when he was messing with the fuel pump, and that gunk has clogged up the filters and the fuel pump, so I might as well order a new filter, fuel pump, and while I am at it, fuel sending gauge.

So here is where I get to the question about the improper seal. While researching the parts I need, I ended up watching a video about the fuel sending gauge and how you can test it, so I decided to do that myself, but after removing the retainer I found the rubber gasket is sitting on top of the pump assembly, when it is supposed to be between the pump assembly and the fuel tank. Now, I could be wrong, and the gasket could have simply become dislodged and ended up in the wrong spot when I was taking the retainer off, but my question is... *if* this mechanic put the gasket on in the wrong spot, thereby eliminating an airtight seal, could that cause the problems I have been having since Monday?
