Fuel Pump "Y" Connector

[TX '90 ZR1]

Anybody know where to get the "Y" that connects the fuel pump lines to the outlet?
Discovered mine has a small crack in it and is losing pressure.
It is the one connecting the 3 hoses together on the sending unit assy. Believe it is 5/16" on the pump sides and 3/8" on the outlet side.
Also, what hose does everybody use to replace the original on the sending unit?
Thanks for the help.
