I have seen many threads on people advising to do this if you are taking off your manifold or modifying etc, well I am.
I would like to know is it a diy job with pipes, hoses, or can you actually buy some sort of kit?
Is it a nightmare job and is it worth the extra expense/grief?
Thankyou in advance for your advice.

It's a few hours work. Not a nightmare by any stretch of the imagination, but cutting high pressure fuel lines can make you a bit nervous if you're not confident in your spannering abilities

As for whether it's worth it, it definitely helps the engine if you're running higher boost/fuel pressure. The standard series fuel rail results in cylinder number 3 always running slightly leaner thanks to it being last in the queue for fuel. Converting the rail to parallel supply solves that problem, giving more consistent fuelling for all four cylinders.

Edited to say that the guide on Ravensblade Impreza (here) will tell you pretty much what you need to know. Also try searching here on the words parallel and fuel
