This fully assembled universal wiring harness works with SINGLE PUMP STANDARD SURGE TANKS ONLY. It is NOT compatible with Standard Surge Tanks that have two internal pumps.
Standard Fuel Surge Tanks can be found HERE
This harness is also compatible with all models of FST-R
The harness includes the proper bulkhead connector to screw directly on to the mating connector on the Radium Standard Surge Tanks (including the Radium FST-R).
It also includes a environmentally sealed relay and mini fuse holder. A 20AMP fuse is included.
Note: a higher current fuse may be required if fuel pressure is run excessively high. Also included is a environmentally sealed relay.
For wiring, all that is required is a source for the FST fuel pump(s) trigger signal. Fuel surge tanks typically use the main fuel pump's relay trigger from the ECU. The other two connections for this harness are 12V power and chassis ground. These leads both use 5/16" (8mm) ring terminals.
The high temperature braided sleeving is flame retardant and is rated for over 250 Fahrenheit. All wires are labeled for ease of installation.
Wiring run lengths are shown below. If these lengths do NOT work for your application, the wires can be cut/extended as needed at the installer's discretion.
If wiring is needed for a dual pump fuel surge tank, please see the Radium Engineering DIY wiring kit (order one kit per surge tank pump):
