1- Connecting power and ground wires directly to the actual battery terminals is absolutely critical. Regardless of where the batter is mount, the EX-EFI power and ground wires must be routed to and connected to the actual battery terminals. Connecting to common grounds such as the frame or engine will NOT work. Connecting to power distribution or stater or fuse blocks will NOT work. Do not think you know better and disregard! Follow this direction exactly!
2- Fuel pumps must always be mounted lower than the fuel tank internal pickup point to ensure positive prime at all time. The safest place to mount the pump is lower than the fuel tank. Running a pump dry can shorten pump life or cause pump failure.
3- Pertonix Ignitor !!! Notice: Most multi-strike ignition modules typically feature a "tachometer output" signal, which is compativle with EZ-EFI as described in the instructions. If the multi-strike ignition does not have a tach output, such as the Pertonix Ignitor III, it will not be compatible with EZ-EFI
Well me and my girlfriend had a day off and decided to take a road trip to Late Model Restoration. Let me tell you, we had the best CUSTOMER SERVICE ever. Jay was very helpful and knowledgeable about the parts I purchased. The showroom was clean and inviting. Also I got to meet JMAC that host's all of their YouTube videos. They also had project BLUE COLLAR in the parking lot, and it is NICE. I will recommend Late Model to everyone I know...
