EQ Systems leveling jacks

[Spacecadet17]

My 2017 Ventana LE has the EQ Systems equipment. In investigating the cause of my system leak I found that the driver side front jack has TWO return lines from the bottom of the jack canister, while the passenger side front unit only has ONE return line. Likewise, the driver side rear unit only has ONE return line and the passenger side unit has TWO return lines.
The driver side rear unit is leaking fluid out of the port that would have been used if this jack had two return lines, but it is obvious there never was a second line. It looks like a plug has come off and allowed fluid to flow out each time it is cycled.
Does it make sense that two jacks have double return lines each and the other two only have one each?
Also, does anyone know what type of plug would go into that unused port?
EQ Systems responded by email from their CS that I might need a 7493 DV-2 kit. Whatever that is. Communication with them is very frustrating
Thanks for any advice

Yes it makes sense. You only have 2 return lines at the pump assembly, so the jacks are in tandem for return only.

Since my pump assembly has SIX lines emanating from it, I assume FOUR are pushing fluid OUT to the jacks and TWO are RETURNING fluid from the jacks in parallel. Therefore, none of the lines emanating from the pump assembly are for slides.

Sounds like that's right.

I tried calling EQ Systems and emailed them. They never responded. I guess I need to drive to Elkhart to get a response.
