Fuel Rail & Line Routing Diagram - Feed Line to Aftermarket Pressure Regulator

This document is a simple hand-drawn (computer-sketched) schematic showing the routing of fuel lines and fuel rails on an engine, viewed from above. Two parallel fuel rails are drawn in the center, labeled "rails." On the left side, curved hose sections connect the two rails together, with a triangular fitting (likely a fuel filter or distribution piece) at the top left junction. A long hose running along the top of the diagram is labeled "This is the feed line," indicating fuel supply into the system. On the right side, two "Shorter lengths" of hose exit the rails, and an annotation with arrows states "Both of these to to an aftermarket pressure regulator," showing that both short hoses route to an aftermarket fuel pressure regulator. A large downward arrow at the bottom labeled "Front of car" establishes orientation of the layout. The diagram contains no part numbers, torque specs, hose sizes, or vehicle/year identification. A reader can learn the general plumbing scheme: feed line into the rails, rails cross-connected on one end, and both return/output lines from the other end routed to an aftermarket pressure regulator, oriented relative to the front of the vehicle.
