The have fuel rails. Solid pieces of metal (aluminium I'd think mostly) with the centers bored out. To which the injectors attach to.
Now, as I've said, to get more fuel from these injectors, we must raise the fuel pressure. After purchasing a second hand SX Performance rising rate fuel pressure regulator I began to investigate how to plumb it into the system.
I did think of a way, but honestly, that would just make more of a mess. Mess isn't simple, or necasarly effecient. So, here is my grand thought:
Remove all of the manifold mounted fuel lines. Then make up a some fuel rails. See attached for how they could be made. Then, the whole system can be plumbed to the FPR via some nice stainless braided hose.
I think it will both clean up the engine bay (appearance wise) and allow for more effecient, higher pressure fuel, to be delivered to our injectors.
