Ferrari Mailing List: Re: Found 308 no-start problem (unbelievably simple)

[George (ygpz4re]

Thinking about it, I wonder if that's how constant pressure is maintained?  A Y going to each rail may require a much higher pressure fuel pump to keep the correct pressure going to each rail.  And hard acceleration might force more fuel to the rear rail. Of course, that may also be said about the sequential setup....

Just a thought (or three).....

Hi George,

 

There is a specific reason why it has to be done this way, but I don’t remember what it is!! Helpful hey?

Peter,

 

From the photo, it looks like the fuel delivery goes into one rail, feeding four throttle bodies, then makes a U-turn to then feed the other rail and the other four throttle bodies - very similar to the fuel delivery in the carb set-up (carbs are not fed in the same pattern, but are fed sequentially).

 

What I wonder is why there wouldn't be a Y connector so the fuel is fed to each rail simultaneously, vice sequentially?  Or maybe I just misinterpreted the photo....?

 

Thanks,

 

George P.
