Good news. After 3.5 years she came alive today. The Sniper started the car with just a twist of the key. I did have a significant fuel leak at the fuel tank module which I am hoping is the NPT outflow fitting and not the foam seal to the module itself. I didn’t realize the NPT fittings require sealant so will put that on tomorrow. I can’t drive her to really test her as I still have the rear brakes and suspension to rework.
For those looking to install the Sniper themselves I would say if I can do it, you can do it. I installed the Hyperspark setup (box, coil, and distributor) with the Sniper and the retro in-tank module, so mine was a little more involved, but not complicated. I have a lift which made it a lot easier, and I had to pop out the rear windows for access, but between the Holley videos and YouTube install videos it is pretty straightforward.
Not great video, but great for me!
