I don't know if you've followed the whole "fuel return line" fiasco with us weber owners, but it seems that the fuel return line at the fuel filter siphons the gas out of the carb when the Jeep sits overnight, causing you to need to turn over the jeep a few times in the AM to get the fuel up to the bowl, fill the bowl, and start the jeep.
I have disconnected the return line, and plugged it, and now I use simply the line from the mech. fuel pump up to the weber. Some people say that you will get vapor lock as the fuel is not circulating, but I haven't had any problems yet, and I know other people who run this way without issues. I tap my gas once in the AM to shut the choke, and she's running on the first revolution. I tell ya, with the weber, the GM HEI dialed in, the return line blocked, and the rebuilt 258 installed, my jeep is really becoming a normal running vehicle.
It starts good hot and cold, idles good, has good power, and runs well every day, not every other.
