While the truck was warming up this morning, I noticed a small spot under the fuel filter. I watched for a bit and it's definitely leaking around the fuel filter drain valve. Should the o-ring be replaced periodically or is this an anomaly?

Is it tight?

Is it tight?

Yes. Double checked. Thinking may need to replace the o-ring, but not sure what size it is yet.
