Id first remove that in tank toyota fuel pump. The vibration could be the engine working extra hard to draw fuel past a restriction, or an air problem or something.
There could be all kinds of stuff with that pump that might harming fuel delivery. I had a problem on a swap once (not toyota, I think it was a VW 1.6 diesel repowering from gas) where all our issues turned out to be caused by a one way check valve between the supply and return lines inside the fuel tank as part of the in tank pump assembly. We had physically removed the pump itself, but had left the assembly to act as supply and return stand pipes.
In that circumstance, the check valve was designed to close with pressure from the stock pump, but when fuel was DRAWN from the fuel feed by the mechanical diesel, the check valve line would open to return, dumping air into the supply line. Of course, it would only do this if you had 3/4s of a tank or less, or if you really whomped on the pedal.
Took forever to pin down, it just looked like an extra piece of supporting plastic between the two lines, it wasn't until I was taking the thing completely apart that this little check valve, and an actual connection between supply and return presented itself. We ended up removing the whole thing in favor of a straight tube for supply and a port for return.Removing that pump and any in line fuel filter underneath would at least remove that variable so you have a essentially stock mercedes like fuel system to start for diagnosis

have the valves been adjusted?
