Fuel System Part - What's It's Correct Name & Where To Buy It?

[LuvNLife]

I'm revamping the fuel system under my '87 GMC shortbed fleetside. The current setup is jury rigged so badly, it seems easier to just replace it.

The truck was EFI, but that's gone now in favor of a carb. The truck has twin fuel tanks, but only the passenger side is running. The former owner converted one side of the the dash tank switch into a kill switch, and we can't quite trace it all out. So, here's where I'm thinking of going.

I'd like to add a pair of low pressure, 30 GPH external electric fuel pumps, wire them both hot, then wire the grounds to twin rocker switches I'll put under the dash. I'll also install a pair of fuel gauges to go with them. That part is pretty straight forward. But, I need some type of "Y" junction to run the two fuel lines into, with one outlet to the carb. I have zero idea what that "Y" is called or where to find one.

Any thoughts or leads would really be appreciated.
