High Pressure [v6.1b] Access

: High-pressure lines often use M16x1.5 inverted flare fittings or metric O-ring adapters.

: High-pressure fueling often requires specialized components like an LTX high-pressure fuel pump , which is essential for big cam tuning but requires precise installation to avoid fueling issues. Hydraulic High-Pressure Lines High Pressure [v6.1b]

: It is critical that all air entering the engine is measured by the MAF sensor . This includes air routed through the Positive Crankcase Ventilation (PCV) system. : High-pressure lines often use M16x1
