Default zr1 fuel pump sender? do zr1s have twin fuel pumps?

Im an lt1 guy, and am curious is the fuel sending unit on the zr1's are different than lt1.

Specifically, I heard somewhere zr1's had twin fuel pumps? is this so?

Does that mean you could put in two walbro 255 l/hr pumps in place of those for some real fuel pumping capacity?

Yes, the '90-'95 ZR-1s have two fuel pumps and yes you could put two Walbro 255 L/hr pumps in it. You can buy the fuel pump sending unit here:

And the Walbro fuel pumps here:
