Fuel Pressure Bleed Off Resolved

[TX '90 ZR1]

This issue may have been previously addressed, but I did not locate it in the archives so am posting it here for reference.
My '90 was not holding fuel pressure in the system after engine shut down. First thoughts were injectors, followed by fuel pump check valves and fuel pressure regulator. All these checked OK.
I traced the leak to the plastic "Y" connector on the fuel pump/sending unit assembly. It is the connection from the two fuel pumps to the pressure outlet. Photo attached. It is the part in center of photo.
The plastic "Y" had separated a bit on the bonded seam of the outlet that went to the secondary pump. I am assuming plastic submerged in gasoline will not last forever, you think?
I did a repair to the seam, but am looking for a more permanent solution. Will advise when I come up with something.[ATTACH]z051918-01.jpg[/ATTACH]
Hope this might be of help to someone experiencing the same issue.
