My fuel line is leaking right out of the connector that connects to the end of the fuel filter. From the tank side. I would like to know if anyone knows of the size connector I need to replace it. The fuel line is good all i need is a new connector. I was thinking it was a 3/8 to a 3/8 but would like to make sure before I order it. Below is the link to the one I think would be right.
Any help would be very much appreciated.

3/8" to 3/8" is the correct size.
Is it leaking because of failing O-Rings, or is the connector cracked or damaged?
I ask because replacing the 2 O-Rings inside of the connector may be easier then replacing the connector itself, that and with this is with that connector I am not sure you will be able to get the connector to connect back on the fuel filter, because once you cut the old one off, your line is going to be about an inch or so shorter than it was.
I had to do some repair on my fuel line not too long ago, and I had to go with another solution, of course I had a pinhole in the line not far from the fuel filter area.
This is what I went with, I actually bought two of them so I'd have a new connector on each end, as sometimes just removing these can cause leaks, not in all cases, but it is possible.
You can cut the line a bit further back from the filter, and cut the replacement line so it is still the right length.
Note, it was not easy getting the old line attached to the brass connector, you need to find some way to get the line warm enough so it expands, and slips down on the fitting, of course you cannot use fire, so the only thing you can safely try is some hot water.
Is the line that is leaking on you the one that is about 2 feet or so in length?
If so you could take it off, take it inside, let it air out a minute or two, and use a hair dryer, or heat gun, I personally quickly passed mine over the flame of a propane torch, but you have to be quick, and careful, or you can ruin the line/connector.
Here is the thread I made when I had my issue, sorry there are no pics in it, but there should be a helpful tip or two.

Very welcome.
The line you are having issues with it the 2 foot or so one going from the tank, to the fuel filter right?
Or is it the one going from the fuel filter to the metal fuel line?
When cutting it to fit I'd lay the old line side by side with the new lines, and take in account the brass union will make things about a quarter of an inch longer once the lines are joined, having it too long is better than having it too short, as you can take it back inside and shorten it, just be sure not to cut it too short as you'll have to order another fuel line repair kit and start over.
Be sure you relieve the fuel pressure, and wear eye protection, better safe than sorry when working with fuel lines!
