i know because i opened the carb after the truck sat for lets say, 1 day.
Fuel bowl was almost empty, level was below the main jet.

I started to make diagnosis and test once i found the truck was not easy to start, always took a while, almost emptying the battery all the time. This is like that since i brought back the fuel system up to "factory" spec, ie, working oem fuel pump, por-15'd tank and lines.

Before i was using a gas can straped to the top of the carb and everytime we used the truck and after we took it out so we never noticed that the carb was leaking like that once it sat for a while. You can see this red neck fuel system on most of our videos on youtube. Thats it.

As i said, i found the source of the leak. I try for now some rubber o-ring since the new copper ones hasnt done the job quite well 3 times.

I also reduced the size of the jet, from 0.100 down to 0.092, the truck was running 11.2:1 afr under acceleration, (not idle)(measured with my wide band oxygen sensor). Now it is near 12.5, much better....
