Trying to think what could be causing this. Seems like the following could be causing fuel to spray out of the injectors on #1 & #3:
1. Injectors are opening at too low of pressure (already disproved this as being the problem)
2. The spring, shim arrangement on these ports is too strong thus holding the port open.
3. There is some sort of solid debris on the face of these two ports holding them open.
4. These ports are somehow damaged (face of port not flat) allowing fuel to pass by when the diaphragm is push up against them.
When I looked at the ports it did look like at least one of them had a notch in it for some reason.
