Basically i want to know if i can somehow still use the standard fuel rail and try and make it work with what ive got, but i imagine i would have to have the standard fuel tank to link it all up with all the bits inside?

this might explain it better

I have all the original engine loom and its all connected up, just have to splice it to the ecu. I intend on using an aftermarket ecu, the vipec v88.

This is pretty much the last piece of the puzzle so any advice is appreciated.
