Late model challenger power steering hose size

Can anyone tell me what the hose size is from the power steering cooler to the reservoir on a 2010 Challenger R/T (5.7 6 speed)?

I'm assuming it's 3/8" based on online pictures I've found. But I'm having a hard time telling for myself because I'm 1200 miles from my car at the moment

thanks

The return hose is 3/8" from the cooler to the reservoir. I used a 3/8" genuine magnefine filter and it's been working great.
