Default Poly Tanks w/ EFI?
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)?
