Poly Tanks w/ EFI?

[EsFors]

I’m planning a future upgrade to EFI and I’ve seen it stated many times that you should upgrade poly tanks to aluminum when making the switch. Others say their poly tanks work just fine with their EFI.

Can anyone tell me why I shouldn’t keep my poly tank and use a Holley Retrofit In-tank Fuel module (19-350) with a poly tank shim kit (12-877)?

The only advantage to the aluminum tank is that it is pre-drilled for the Tanks, Inc, pump and pick up. Otherwise, I see no reason to change it.
