VR2 Nozzles, Vapour Return Hoses and Manifold
VR2 nozzles and hoses are significantly different to their non-VR2 counterparts.
The released vapour is recovered by special nozzles which ‘suck’ it back into the hose
(see Figure 26).
VR2 hoses are coaxial and carry the recovered vapour in the central portion while fuel
flows through the outer section. The vapour is directed to the vapour return hoses by
coaxial adaptors situated at the junction of the delivery pipes and hose assemblies (see
Figure 27).
The vapour is taken from the adaptors via a manifold and return hoses to the vapour
sensor/meter assemblies.
