grab the straps from the S5 tank since it's larger and you'll need to swap your fuel pump/sending unit body into the other tank since the S5 has the 4 pin connector on top of the sender where the S4 has bulkhead connectors on it instead(S4 sender is more reliable when modded with upgrade fuel pumps).

yea, you will need the straps to match the series of gas tank you are installing. if you have an upgraded fuel pump i might also consider getting the sending unit with the tank and hardwiring it to your car.

Ya.the Tops of the Tanks(re: sending units) are different on an S5 compared to an s4.
You are also going to notice that Tank capacity is different too.That is why you should get the Straps with the tank that you put in.,just in case the Straps on the car turn out to be too short(or too long).
Get as much Wiring off the car as you can.(pump/sender harness From the car)
The S4 has a Connector wire that runs from the Front of the Rear strut wall to the tank,and then it is connected again to the sending unit.
The S5 is just connected at the Tank.,,and the connector is different too,than that of an S4.
