Fuel rail, but yes, speak in specifics. YMM

Shifty:
What they said, the fuel system is either returnless, and dead-heads at the rail, or has a return line.

Stewart G Griffin:
Not sure about specifics.  i meant in general.

Let's say for a LS3 crate engine.


Actually, why don't we just discuss both styles----return and returnless.
