Jon, thanks for the reminder. I do have a good Carter Competition 750 AFB on the shelf. I honestly don't recall if I bolted it on while dealing with the boiling fuel issue. However fact is I think it was more a case of heat radiating off the pavement, a lot of engine in a small compartment and heat soak of the carb that caused the issue. As mentioned, no ethanol or go fast enough to keep the engine compartment cooler and no issues.
On fuel pressure, I was running a electric pump with 50 psig output and a Holly pressure regulator with a 4.5 or 5.0 psig output. To operate the FiTech I just pulled the pressure regulator and added a return line.
I do love carbs, but Fi does have it's place, at least in my shop. That place would be on a engine that starts instantly no matter how long it's been setting, runs the proper AFR all the time, and gives a easy way to tune a number of pramaters with ease.
Now the 340 Duster
hereis perfectly happy with its phenolic body spread bore carb.
Am I advocating Fi for our truck? No sir, not at all.
