CIS injection question

[VNorman at TelecompSys.com]

On every CIS injected car that I have seen, there has always been a fuel
hose from the fuel distributer to each injector. So..an I5 engine has 5
hoses etc. My question is - why? Since all the injectors are merrily
squirting fuel all the time when the engine is running, wouldn't it save
money to have a single fuel hose into a fuel rail connecting all the
injectors, just like the typical pulsed injection system?
The Bosch guys are a smart bunch, so I'm sure there's a good reason. Can
anyone tell me what it is?
