New steering pump and still leaks power steering fluid. Do I need a different pump or Lucas stop leak?

[txaggie]

Howdy all,

My power steering on this truck has been the bane of my existence. The pump is a new lares 12348 and I have custom high pressure lines made because my newly purchased high pressure lines kept splitting.

We also have a Borgeson tight gear ratio box.

My issue is that it leaks like crazy which looks to be from maybe the lid on the pump? I ordered a new pump cap via lares and it will be here Monday.

Should I put some Lucas power steering leak stop in this too? What’s the detriment of it?

Should I change the pump style? What do y’all think?

It looks pretty dry in those pictures?

Dried it off but after a bit of driving it looks like it comes out of the cap.

Over filled? Maybe the dip stick is wrong?

Is there any detriment to the stop leak Lucas?

Nope. But if the cap is the culprit, it won't do anything for that.

I would consider a new rubber seal ring inside the cap. Do you have air in the system? I have a '65 Thunderbird that will was shooting fluid out of the cap until I remedied it, it churns like crazy in there with air bubbles.
