Fuel tank connection seals

[Macrobb]

On my trucks, there is an O-ring sealed connection between the plastic fuel line and the tank sending unit.
The plastic fuel line piece just slides over the steel "nipple" at the end of each line coming out of the sending unit, and then a retainer is added to keep it in place.

I'm a little concerned about the o-ring/seal in that plastic piece.

Is it possible to replace this?

Or, is there some other better way, hopefully something better than just whacking the end off and using a bit of rubber fuel line to connect the two.

Thoughts?

Ive done just that, replaced it with rubber hose, the plastic gets real crusty in the Texas heat

I've replaced them. Think it's in my thread here in the PSD section.
You can also just get the new nipple.

You can get new an fittings for them, or barb fittings to connect hose. One is 5/16 the other 3/8 I believe. I actually removed them and just ran rubber diesel rated hose to the metal nipples with double clamps. Never had an air intrusion issue. I saw them as air leak risk when I replaced the tanks.
