Fueling & Injection - tank question

i want to put a platic tank in my lt1 car..which if any ls1 plastic tank car(99-02) have a return style system...to the tank...lt1 have a pressure line return line and an evap line i think is what its called for ventillation (which i have removed so its not necessary)

ive heard of others doing the swap so im pretty sure its possible, just need to know how
thanks

All the 99-02 tanks are the same but they do have a feed, return and a vent on the sender. Why put a plastic tank in your car? The steel tank is much easier to work with when installing pumps.

weight...hear they are about 20 pounds less...

because you can put an adapter to run a bigger pump by drilling a hole in the bottom of the plastic tank? you have to sump metal tanks
