So what do you put them on? Unlikely anyone already has a flush, so let's say 10%. Think someone has a 4? Possibly, but I wouldn't think likely, let's say another 10%. That leaves overpairs - i think there's 50% likely to be at least one here - and high diamonds, say another 75%.

So, if that's the case, you aren't likely to be ahead now, you are even less likely to be ahead if random overcards fall, you won't be ahead if a diamond falls, and in fact you really only have the 4's as outs, with redraws possible against you if it's not the 4d.

You're likely to get good action from a higher diamond if the 4d drops, and you're likely to get some, if not a lot, of action from an overpair if any other 4 drops, so you have some implied odds, but they're not really that good. If you assume you're going to get action if you hit, you have to assume you have little bluff equity as well.

So, you're getting roughly 2.5 to 1, you need roughly 9 to 1, perhaps 4 to 1 or 5 to 1 after implied odds. Dump it and move on.
