Phantom Series: 1999-2004 GM Truck Direct Drop-In

$483.29$627.49

This system is designed to work in plastic
fuel tanks only; some of the 1999 models still used a steel tank. The
1999-2004 models used a smaller factory fuel sending unit than the
later 2005-2017 models. The smaller size limits the pump
configurations that this tank will accommodate. These tanks will
accommodate; single 340, dual 340, and single 450 pump
configurations. Any other combination of pumps will physically not fit
through the factory sending unit hole. The Silverado and Sierra tanks
have a tank depth of approximately 14.00”, while the other models are
more shallow and have depths around 8.25”. The new system will
accommodate both of these tank depths. The 2500 truck models can
have a deeper tank up to 17.00”; the system will also accommodate
these depths as well. This product is not legal for sale or use on emission-controlled vehicles except when used as a direct replacement part matching OEM specifications.

Description

  • Must be a new body style/plastic tank for the model year 1999

Installation – The system is based on the Phantom design where the
customer will install the pumps at the correct depth for their particular
tank. The outlet cap is what makes it unique from the Phantom. The
outlet cap is a direct replacement for the factory sending unit outlet
cap. The new cap consists of 4 – ORB -6 female ports (main pump,
auxiliary pump, return, and vent), as well as three sets of electrical
terminals (main pump positive and negative, auxiliary pump positive

and negative, and level sender signal and ground). The ports on the
outlet cap exit vertically due to height limitations from the lock ring.
The ports can be used with PN: 15689 (Direct Port Male 90 Degree
Fitting). The outlet cap will come assembled with all the wiring pigtails
and hoses attached. The hoses are left long and will be cut to length by
the customer in order to be set at the correct depth. The pump hanger
brackets will be cut to length as well. The single pump configurations
use an offset pump hanger bracket, the dual 340 pump will use the
same pump hanger bracket and spacer the original dual Phantom did.
The large sized foam (8.50”) is used on all these applications, it installs
the same way as the original Phantom, cut the foam 1.00” longer than
the tank depth when measured at the original sending unit hole
location. The customer will use the factory fuel sending unit lock ring
and gasket to retain the new pump assembly in the tank. The lock ring
can be reused, but they must use a new factory replacement gasket
(not included). Plumbing the system will be the same as the other
traditional Phantom configurations. The system will require heavier
wiring to power the pumps; the factory fuel pump wire cannot be used
to power the new Aeromotive pumps. The system does not use any of
the factory vent, emissions, or tank pressure sensor. The engine
tuner/customer will need to delete these functions from the factory
ecu (if used).
Float Level Sensor – At this time we are not including a float level
sensor or bracket with the pump assembly. This is due to the variations
of float level sensors and how they mount to the factory sending unit
assembly. If someone has purchased an aftermarket sending unit
assembly, the float level sensor may mount in a different way than the
OEM version. Until we can either source a universal sending unit with

the correct ohm range or find a mounting solution for each of the
factory sending unit types, we will not be including a bracket for the
sending unit. We do have preliminary design for the Silverado’s and
Sierra’s that seem to be very consistent among all of the sending units
that we have seen so far. If someone calls with one of these
applications we can build them the correct bracket for a factory sending
unit. The bottom of the outlet cap will have two wires soldered for the
level sender that the customer can use to connect (with provided quick
disconnect connectors), to their factory sending unit. If we can offer a
sending unit bracket for the particular application, the customer will
need to cut a “window” in the foam to allow the sending unit bracket to
pass through and position the fuel level sensor outside of the foam. To
install the system with a sending unit bracket, the fuel level sensor and
bracket are first inserted through the “window” in the foam and left
loose. Next, the pump assembly is inserted in the factory sending unit
hole loosely. Next, plug in the two wires from the factory sending unit
to the two (white) pigtail wires attached to the bottom of the outlet
cap. Once the sending unit wires are plugged in, you can attach the
sending unit bracket to the bottom of the outlet cap with 2 – 10-24
screws. Finally, push the entire assembly into the (once a new gasket
or o-ring is installed), and secure with the factory lock ring.
