A
Fuel
Pressure
Gauge
is
an
important
part
of
every
car.
Use
this
gauge
to
monitor
your
fuel
pressure
levels
and
modify
it
if
you
have
an
adjustable
fuel
pressure
regulator
(FPR).
Please
be
sure
to
adjust
your
pressure
accordingly
either
to
the
service
manual
or
your
own
preference
before
any
kind
of
tuning
or
operation.
