FI recommendation for 360 Dart

I used FItech on both my Scamp and also on my 1979 D150, Installation was pretty easy and straight forward and there tech support was pretty good. What I would recommend is doing your research on the installation of any kit you buy because from me talking to various aftermarket fuel injection makers (Holley, FITech) the vast majority of problems seem to come from people doing less than stellar installations, An example of this is in the instructions from my FITech kit, It has a whole page of what not to do during installation of there kits to include and I am not kidding (do not use house Romex or house wire nuts), and to be fair I do feel that retrofitting FI on to our old Mopars is still a hit or miss proposition but as more and more company's are doing the R&D to make there respective systems more robust/reliable they are getting better. For me it all boils down to how well you do the installation, take your time and do it right the first time. Good luck and hope this helps

P.S. if you are replacing your tank please check out a company called Tanks.inc they make a direct fit tank with the cutouts for an in tank fuel pump.
