Features

Norgren GT Development’s Return Flow Splitter
is used in many of today’s Class 8 vehicles to
evenly distribute return flow of fuel to the fuel
tanks, eliminating the need for a crossover line.

This innovative product for dual draw, dual return
fuel systems was introduced in the early 1990’s,
and has been adopted as standard equipment on
a variety of vehicle makes. This patented product
features identical variable flow openings to
control return fuel flow which will, with a properly
designed and maintained draw system, provide
proper fuel balance in dual tank systems.
