Hello,
In the example given, 4 injectors drawing 2A would end up being protected by a 15A fuse.
Only in older type of EFI are all injectors firing at the same time. I witnessed starting from the eighties (LE-Jetronic, Motronic, Ford EEC IV etc) the injectors are fired in batches of 2. so the wiring will only have 2x2A (in the case of a 4cyl). With a 150% margin for selecting the fuse, it will give us 6A, so a fuse of 7.5A will do.
This is how I would approach the sizing. Any feedback from others on this one?
Do it. If you have a problem, you can always use a larger fuse.
The goal of the fuse is to protect the wire, and normally the wiring for injectors can handle 15 amps.
