They might need to change the cooling on the fuel system, but that might add more weight to the RB18.
Keeping the temperature of the fuel within a certain margin to avoid a fuel lock shouldn't be too difficult for Red Bull to solve, but it might cost performance. We'll find out at the weekend I guess.
Isn’t fuel cooling not legal?
yes, it's illegal. The only thing the teams can do is cool the fuel before it goes into the car, and even that has a limit.

6.4.2
No fuel intended for immediate use in a car may be more than ten degrees centigrade below
ambient temperature. When assessing compliance, the ambient temperature will be that
recorded by the FIA appointed weather service provider one hour before any practice session
or two hours before the race. This information will also be displayed on the timing monitors.
The temperature of fuel intended for use in a car must be measured via an FIA approved and
sealed sensor.
6.4.3
The use of any device on board the car to decrease the temperature of the fuel is forbidden.
Ten degrees centigrade below ambient temperature is not really cool, that can probably be handled by running it through a short, finned metal line which could be 100g more than the plastic one it replaces. Its not all the fuel that has to be cooled, just the spall amount going to the pump at that time.
This is ofcourse relative. After dark in a cool place or mid afternoon in the tropics wil be very different
When arguing with a fool, be sure the other person is not doing the same thing.
