FiTech EFI system

Im debating about picking one of these units up. After reading thru this entire thread, I have to say Im very leery. It seems like a lot of messing around just to get it to run correctly. The reason I was thinking of going with this unit is because Im tired of messing around with carbs. Well it seems like there is a bigger risk of getting stranded or not running correctly with this. Like Johnny mentioned you dont hear about the people that are happy with it, just the ones that are having problems. I was also under the impression using the FCC you didnt need to run a return/vent line and now I see you do. My tank is not set up for it and if this is something that must be done then that is even more cost to the system. I guess Im looking for someone to convince me to go with this unit now. Im also curious if anyone has seen an increase in MPG's out of this.

I'll answer any questions you have, but I'll let the masses jump on this one so you don't feel "over-sold".
Between these and the snipers...anyone with the basic ability to install a distributor, and set timing with a light, should have minimal issues as long as you follow instruction. For what its worth...the "vent" line is much smaller than an actual return line, and doesn't have to be fancy since its not continuously pumping fuel. On my dart (and i think others?) the filler neck pulls out pretty easy. You could very easily tap a small barb fitting into the base of the filler neck with it on a work bench, where there would be no risk of metal filings an such.
