Scavenge Tube
A 1/4 in PTFE tube (shown in orange) connects the WHASP Tank to the
compressor inlet valve. Vacuum from the compressor pulls the separated oil
from the coalescing filter, recirculating the oil in the system (Figure 48).

Pressure Control Tubes
A 1/4 in PTFE tube (shown in green) connects the discharge valve to the
lower fitting on the side of the compressor inlet valve. This provides the
system air pressure (factory setting 150 psi) to operate the inlet poppet valve
(Figure 49).
