You will have to replace the entire fuel filter, it's not cheap. Last time I asked Al-Hamd Autos in Gizri for the OEM one I was quoted 8,000rs+
But why are you replacing it? What's your fuel average nowadays? Nah, don't change the engine oil yet, complete 4,000Kms and then flush it entirely.
Yup, that's the picture I sent you. BTW, I lost your number since my phone got snatched a few weeks back, mind texting me, thanks!
