Curious about fuel systems?
I was recently very curious about fuel system set ups on high performance cars, particularly Subarus, and so I tried to find some information about the full system. Whilst I had a vague idea of how the fuel system works in a standard car, information about systems in race cars seems to be very sketchy and hard to come across.
After a few hours of research and looking blankly at diagrams with information that meant nothing to me, I managed to come up with this little diagram: (Apologies for the small size, hopefully people can still read it)
Obviously I have very little knowledge of this kind of thing, so I was wondering if anybody could help me out with anything I've missed off, or an overview of how a system would be set up in a race car.
Cheers,
Andy

A lot of people when uprating their fuel system use a parallel fuel setup rather than a series fuel setup. To do this your diagram needs to be modified so that the HP pump and filter feed to both rails and the FPR is at the other end of the fuel rails providing the return.

The outlet from the filter would split with a T piece through the injector rails then T piece back to the FPR and return to the tank. Fitted a setup to my Bug about 4 years ago.

This is similar to the system I fitted might give you a bit more of an insight.
