Default Fuel return line possibilities?

Alright so I am going to be making the switch to a EFI system but as of right now its about half and half for who requires a fuel return line. I would prefer to go for the FAST EZ-EFI over the Powerjection 3, it just seems to be more reliable and user friendly system from what i've read. The downside is the return line needed.

Has anyone done a return line system that does not involved drilling into the tank? I would prefer to do a less invasive install, and have heard about people being able to put the return line into the filler neck on other cars. Is this even possible with the tank being sandwiched under the body?

Thanks!

THIS IS WHAT I AM DOING WITH THE EFI CONVERTION.http://www.robbmcperformance.com/pro...vettesend.html
THIS WILL FIT MY 70. MAYBE YOU CAN COME UP WITH SOMETHING THAT WILL WORK AS A RETURN AT YOUR SENDER.

I just emailed them, so we'll see what they say about getting one for a 81 corvette. That would be the perfect solution if they're able to make something. Thanks!

After googling some pictures of a 78-81 sending unit, there seems to already be a fuel return line. Does anyone know if this is large enough to use in a 43psi EFI setup? Doesn't look like its much bigger than 1/4inch.
