Fuel line fitting

Can you get a picture of the fitting that you need to connect too? There aren't specific replacement parts for these with a part number so we just need to see what type it needs to be and then we can find the one that will fit. They are more of a general part that more or less you just find one that will work.

Let us know if you can get a picture and then we can locate what is needed or even come up with an idea that can be a good substitute. Thanks
