Or step up to the 2.0 system which is capable of 1200 as well. Not sure how well the dual carbs would fit under a stock vette hood.
That is the route I went. Dropped my car off at the shop yesterday to get it started. I offered a $200 bonus if they could get it done by Friday night of this coming week (dyno day on Saturday and I would like to have my car) so we will see.

I 've been running the EZ EFI retro-fit kit for several years now, very happy with it

And even of you need a newer tank I think your talking about 279.00 for a new fuel tank that fits the sending unit.

How doe the vent work? It appears it must use some kind of float or something to seal the vent once the sump is full and any air has been purged. I would be worried it leaks so the thing is dumping fuel onto the ground.
Where does a return line go? The thing has a fuel inlet from the mechanical pump a pressurized fuel outlet and a vent so no return line fitting.
It appears to be tailored specifically for use with their E-street EFI systems.
Google search "fuel injection surge tank". There are a few other options such as this;

You can also use a fuel cell something like this;

Run the high pressure pump feed and return lines off the bottom. Hook the mechanical pump feed and return lines to the top.
If you wanted to get really fancy then make a plate to replace the filler with a pass-through bulkhead fitting and hang an in tank pump off it.

I am using an in-tank pump with an internal sump in my stock tank, I have posted my set up several times here.
If you do not use a sump or baffling of some sort, you most likely will have issues at low fuel levels.

You generally will have issues with a low tank if you don't do some kind of baffling or sump.
You should try an Impala with the flat tank. Lucky if it doesn't suck air below 1/2 tank.

I used the 1982 Sending unit in my 1980 and installed the EZ EFI pump onto it , perfect fit no concerns of having 1/2 tank issues at all. I do not want to offer bad info but the 1982 tank .. look and see but it may fit most if not all c-3 models ,, if it does your under 400 for a tank and sending unit ....

The year or type of sending unit or even C3 Corvette gas tank have nothing to do with the fact that there is nothing to hold fuel around the pickup without a sump or baffling. I can almost guarantee that in lower fuel level situations, the pickup will become uncovered during cornering or hard acceleration and the pump will suck air.

My point has absolutely nothing to do with street vs race cars, and how exactly do you know what is applicable for what applications for most members?!?! 
I guess you don't really understand the importance of keeping an EFI fuel pump's pickup submerged in fuel. It isn't really a problem with a carb because the bowls hold fuel. There is no production EFI vehicle that does not use a sump or baffle of some sort in the fuel tank for good reason. This applies to the cheapest of econo cars up to the most expensive sports cars.
Maybe you should tell them that they are all doing it wrong!
