1974 C/10 Project "paw paw"

[orngsikL]

I had typed up another long story, hit a wrong button and it all got deleted.

Picture from when we went pick the truck up, after signing the papers and loaded up to come home:


So here's the short version:

Took the truck on it's first maybe voyage to work (before wax):

Drove it home at the end of the day and found out the gas tank had a few holes:

Replaced it with new hoses, fuel filter (didn't have one) sending unit and straps.
Problem: Fuel gauge reads 1/2 full when key is off, but tank is actually full, and 1/4 full when key is on. Anyone got any ideas??

Installed new plugs, wires, coil, cap and rotor.

Took it out yesterday and it has a hesitation in 3rd while crusing, like it's not getting gas, so I took the fuel lines apart and blew all the trash out.

Now, there is still some hesitation, I think the cab needs cleaning and timing needs to be set. Anyone got any tips on any of this on the inline 6?
