Slow sink faucet drip

Doesn't look like I have options from the top of the faucet.
The cold water line is where the drip is at (I shut off the valve and no more drip).
The way this is constructed it looks like my only option is to replace the entire faucet?

OK , so where's the drip?
Where you adedd the red circles?
If so the most likely cause is someone over tightened the flex line and crushed the washer inside.
That style line only needs to be hand tight, then about 1/4 turn with a wrench.

Apologies for the confusion, I updated the pictures. The drip comes out of the tip of the faucet. The underneath picture is just to show what the configuration looks like underneath

You just need to replace the seats and springs. They are quite inexpensive.

Turn off the water to your faucet. Pop out the plastic cap at the base of the handle and loosen the Allen head set screw inside and lift off the handle. Then unscrew the faucet cap tensioning ring. Lift out the stem and ball and you'll see the two sets of seats and springs in the bottom. While you have it apart you might as well replace both.

Are the seats and springs all a standard size or do I need to take it apart, take the old parts to the hardware store, then buy the new ones?

I am aware of two different styles but they are both similar in size. If you know the brand of faucet it's easy to get the right ones.

Try moving the handle slightly to one side or the other to see if you can make the leak stop. Co-worker had the same problem and we suggested that and it worked.
You may need a new cartridge for the faucet to fix it correctly. If you find that sweet spot where you can shut it off without leaking you are good.

That looks like the new style Delta 400 series. They used to be the best faucet around.
Is that oval base plastic ? The new style Delta uses the plastic oval base.

I went thru three of them. All leaked. Ended up going with Moen.

Anyway.... it looks like a Delta Foundations single handle.
If that is the case..... it uses the dual rubber seats and springs like Dane mentioned.
Very easy rebuild.

I bought every set of "seats and springs" on the shelf.
They're all for Delta, no other brand.
...Hopefully mine's a Delta

Wow, that worked perfectly, I used the second from the right set, I'll return the others.
No more leaking, thank you.
