Electric choke. DGAV with the water choke ("Aqua") uses the coolant temp to sense when the engine is up to temp. It's a little more tricky to plumb but all reports say it works fine. DFEV and DGEV are mirror images of each other, it depends on how you want to route the accelerator cable. Which model is really a matter of personal preference for how you want your truck to look and work.
The fake Weber is a $200 mistake many of us here have made. Costly lesson that you get exactly what you pay for. I made it, too, and ever since, I try not to cheap out on parts and always find out what the country of origin is. Buy cheap, buy twice.
