Talking Re: 1977 GMC CCDW build

So it had been running for sometime but I kept having issues. Driving down the road it would stumble and feel very under powered and going up hills super sketchy and one time she flat out left me standed I poked around found the accelerator pump wasn't working well here we go Carbs are simple and Qjets are very straight forward so got a rebuild kit and tore it down long behold leafs in the fuel filter well then there's the starvation. finished it pulled the tanks all new seals and hoses to insure I was good to go 2 inline filters.
