Fuel sending unit filter/strainer

So went to swap back to my original sending unit from the inaccurate reman that I got from yearone and noticed that there was no filter/strainer on the end of it. 1) has anyone got one from yearone before with nothing on the end of the tube? There are no whiteness marks or anything that even suggests one was there in the first place. This unit has been in the car for just short of two years. 2) do I need to get on to put back on the original sending unit? It’s going back into a fuel tank that has only been on the car as long as the new sending unit was. If I do need one which one do you guys recommend buying and from where? Having a hard time find one that looks like the leftover of one I found on the old sending unit when I took it out the old tank.
