fuel supply line is leaking?

Hi,

Which is the one leaking? Is it the supply or return? See pic below.

If it is the supply, inspect the connector for cracks or the hose for any damage. If everything appears to be okay, you should be able to simply replace the o-ring.

Let me know.

the supply, how do I replace the O-ring?

Often times, the connector is replaced. They make replacement parts that get installed onto the existing hose. On the other hand, once the connector is off, you will see the 0-ring inside the connector. To replace it, I always use a pic to remove the old one.

One out, you have to get the same size o-ring for replacement. If it isn't the same as the original, it will leak. There is a good bit of pressure on it.

Once you get the new one, it's nothing more than reinstalling it into the connector. I like to put (don't laugh) a little Vaseline on the new o-ring to help prevent the chance of damage when installing it.

Let me know if that helps.

PS: Merry Christmas.

how do I replace the connector? Is it better to replace the connector or the o-ring? What kind of pick I need to replace the o-ring? Merry Christmas.

Hi,

If the connector is still good and the only issue is the o-ring, I would replace that. As far as a pic, I attached a picture below of a mechanic's pick set. If you have a Harbor Freight nearby, they sell a smaller set for under 5 dollars.

Let me know.

I have the first 3 and the last pick in my toolbox, are those o-ring hard to replace? the leak not bad how would fuel-resistant sealant work on the connector?

Those O-rings are not bad, any of those picks should work.
