I put a FAST EZ-EFI system on Mater and used it as an excuse to finally dump the stock fuel tank that I was no longer using and all of the dual-tank hoses/wiring/vent stuff. While AeroTank did a good job putting all of that in (and Mater got all new rubber fuel lines as a benefit) I was never going to go back to the dual tank setup and simply have no need for more than the rear AeroTank holds.
The EZ-EFI system came with a Walbro external pump (no in-tank pump option with the AeroTank) and taking out the stock tank gave me that whole framerail to mount things to. With a stock tank only, it would have been interesting to make this work and probably would have required figuring out an in-tank pump setup. Plus is now having AN fittings for everything from the prefilter forward.
Putting it all together was really easy, planning where to mount everything and how to route the wiring/fuel lines really took as much time as the install itself. It's a breeze to set up the system on the control unit and it fired right up and ran great the first time (you have to start the programming with it off and then start it up when instructed to get the engine up to temp before you continue programming).
I'm not going to have MPG numbers as Mater's speedo cable took a dump last year. This was all about drivability. Throttle response and power are incredible. Overall drivability is fantastic. I'd been fighting a tip-in hesitation ever since rebuilding Mater's Edelbrock and it was pissing me off. I'm sure it was user error, but I was sick of diddling with the carb to figure it out. Mater's reason for existence is to JUST WORK and let me drive it without issue whenever I like. I also like knowing the EFI will always keep the fuel consumption as optimized as possible (and I can further tweak the A/F targets if I want) to maximize MPG, even though I know it's always going to be relative with a 360.
Very, very happy with this upgrade. Pump is a little loud, but I knew that going in, more reason to turn up the stereo. Having the ability to play with the display for all the running data and RPM is really sweet.
Fuel pump on the driver's frame rail opposite the exhaust.
installed, computer right by the battery for minimal power wire length and the cool air intake connector is right there basically pointing right at it (not using the duct obviously)
Running screen, note that I have a one-wire alternator on Mater (came with it new in the box) and I haven't "goosed" the engine yet in this photo to excite it, hence the low voltage number, it's 13.6 when "on". Having that displayed on the unit up at eye level is nice.
