Default leak around fuel line connector

I smelled some gas and looked at the fuel line connection and noticed one of them had some wetness around it. However, I can't seem to find a connector or replacement part for this and was wondering if anyone has found a way to repair this. Are the O rings removable?I did take it off and clean it up but not sure if it will come back again.Picture of the fuel lines connection to the rail can be found here:https://www.gmforum.com/mechanical-134/disconnect-fuel-line-283854/

Yes, the O rings are replaceable. I've done it a few times. Just make sure you use gas safe O rings.

mdbonnie,
I purchased a Dorman PN# 800-057 5/16" Quick Connector, Straight w/ 18" of 5/16" Nylon Tube and a Union. Cut about 12" off of the original fuel line and used the union included with this kit to splice into the line coming up from the fuel filter. There is an area up against the firewall that is straight where I made the spliced connection. The quick connect connector on this part looks just like the one on the Fuel Filter side. As a matter of fact I believe that is what this part is used to replace. The Filter side. Worked perfect on the Fuel Rail side. Here is a link to thier Website

Hope this helps,
Mike

So the leak went away when I re-seated but it has came back. The real pain about this is once you pull off the connector and get the o-rings off you know your are out of service until you get it fixed.

I talked to the Napa guys and they said they had a kit so I thought I was all right but sure enough the o-rings they sold me were to small!!

Found informaiton on the exact specifications at the below links.

The old o-rings were in terrible shape. Hardly any effort and they pull apart so it was no wonder I had a leak. But the Napa guys did have a -012 o-ring in a box under their counter and it fitted perfectly. Funny that they had several -012 sizes but it was still easy to pick the right -012 size.

Definitely needed an o-ring pick to do this as it is a tedious job but took me less then an hour. I made my own pick but I can see why it is recommended to buy your own pick. The trick was to put the one in the back first by sliding the ring inbetween the o-rings forward. Once the back one is in slide the ring back snug against the back o-ring and use the pick to put the next o-ring in.

Fitted back on nice and snug so I'm in good shape now.

These o-rings are definitely a problem for a lot of folks and personnally I think it should be a re-call.
