return line question I have a dumb question? (When won't I) I have a 98 ls1 from a camaro,that's going on my nova, now this engine has a return line from the rails. My question is can is plug the return? I will be using corvette fuel filter that has the return on it. Would there be any problems? Issues or concerns I should have?

No why would you? all the newer corvettes and fbodies don't use a return. The only issue I know of is the tune for a non return system is different because the power enrichment is done with the injector pulse.
With the vacuum operated pressure regulator the fuel pressure rises on low vacuum.
So you would use 99 up corvette tune Or a 99 up fbody tune.

one more question??? if im running the fast ez efi ls2.0 and it askes do I have a return style system, do I say yes cause the vette filter has the return in it or no. also will the fast system still be able to do the self tune since it doesn't use vacuum for fuel inrichment.

The only actual change necessary in the tune is in the injector flow rate table, as well as the offset table that references manifold pressure.
