Hello and welcome to JustAnswer!

This could be a couple things.

I'm assuming you'd find the fluid is aerating while the engine is running if you were to remove the reservoir cap. If fluid is aerating then it can foam up and spit out when the engine is shut off.

If it's aerating it could be a line issue. A damaged line or O ring at a line fitting can allow air to be drawn into the system through venturi effect and it will cause what you're having.

You may also have a pump issue. Aftermarket pumps have shown horrible quality over the last 6-8 years and using one almost guarantees trouble. If you used an aftermarket pump then it's most likely the cause.
