Lower fuel line connection... o rings?

[joed]

I hope this isn't already posted but can't find it. I'm reconnecting stock flexible fuel lines to the steel lines near power steering. I don't see any o rings on them. Do they need o rings? I can't imagine I took them off last year when I took it apart, but if I did, I can't find the old ones so more difficult to size replacements.

Do they get o rings? Anyone have sizes?
Thanks.

I have the upper ones, for regulator and fuel rail, found great info on those each time I needed but can't find anything on lower ones which makes me think there are none? However if they follow the others, the smaller line on the lower set should be 1/16 smaller than the small one up top which is 1/4 ID 3/8 OD with 1/16th thick(fits the larger line down below) so 3/16 x 5/16 x 1/16 is my hypothesis

They do get orings. I always go to Napa and get the kit. It's a box with 2 orings. I don't know the part number

Check the other end, they might be stuck in them.

ok thanks, not in the other side of the fitting so I'll check NAPA.
