Abstract

A fuel dispensing nozzle is provided with a view glass/fuel flow indicator that are disposed between the main fuel valve and a downstream check valve. The view glass/flow indicator means comprise a pair of horizontally aligned view glasses. A plurality of embodiments illustrate the use of different sub-assemblies in providing the view glass/flow indicator functions, as well as different provisions for obtaining a seal that prevents leakage of fuel at the view glass units.
