A
fuel
surge
tank
(FST)
is
designed
to
prevent
fuel
starvation
to
the
engine
on
vehicles
with
inadequate
fuel
tank
baffling.
Fuel
is
supplied
to
the
surge
tank
by
a
lift
pump,
which
in
most
cases
is
the
OEM
in-tank
fuel
pump.
The
volume
of
fuel
inside
the
surge
tank
acts
as
a
buffer
to
always
keep
the
FST
pump(s)
supplied
with
fuel,
even
if
the
lift
pump
starves
momentarily.
This
volume
is
maintained
by
the
lift
pump
as
well
as
the
fuel
returning
from
the
fuel
pressure
regulator.
Excess
fuel
in
the
surge
tank
is
returned
back
to
the
vehicle's
main
fuel
tank.
The
surge
tank
also
provides
a
quick
and
easy
way
to
upgade
any
standard
fuel
system
without
opening
the
stock
fuel
tank.
This
is
an
excellent
fueling
solution
for
vehicles
installing
large
demand
power
upgrades
such
as
forced
induction.
Recently
redesigned
for
2019,
the
Radium
Engineering
MPFST
is
the
perfect
solution
for
high
power
vehicles
experiencing
fuel
starvation
during
aggressive
driving.
Multiple
high
flowing
fuel
pumps
can
be
used
in
the
surge
tank.
