The easiest way to tell the supply line from the return line is the supply line has the filter on it. So just follow the filter back and that is the supply line.

Here is a guide that will help with replacing this pump in case you need:

Also, I am attaching the info on the filter as well.

Please let us know what you find and if you have questions.

Thanks
