I say the same thing but most people just roll their eyes at me. I don't miss pre ECM cars. I remember the first thing I was thought when learning to work on cars "It ether Fuel, Air, or Fire & you need to find out which one." This was just to get started looking for the problem. Then you had to pull parts to measure them. Now I just unlock my phone open a app & see which system to look at. Most measuring I can do without ever removing the part. Most fixes never cost me a dime or over 10 minutes of work.Nice job on the fitting. I doubt the type of solder will make much difference in that application. Being a Ford guy you have piqued my interest. What's under the valve covers? Small block Stroker? I'm in the process of converting several of my older cars to e.f.i., and it does take a little thinking, and engineering to get all that data where it needs to go. Really nice when it works though. No hard cold starting, or flooding, along with more power and better mileage.
