I'm at a loss here and could use a bit of assistance. Backstory.... I've been plugging away at replacing the carb and removing all the unnecessary emission components for a couple days. Now can't seem to get the new carb to take a prime. I am starting to think it might actually be an issue with the carb itself. The truck starts and runs if I fill the carb with fuel, also I'm getting fuel out of the line if I disconnect it, run a hose into a bucket and crank the engine. I don't think the decarb itself is responsible for the issue but details of the decarb as follows...
Drivers VSV:
Port Y: Carb insulator with a T for Fuel cut solenoid vacuum
Port X: Intake
Port Z: Evap Purge
Port S: BVSV B
Pass VSV:
Port Y: Intake
Port X: Loops to Dist vent
Port Z: Dist vent
port S: Gas filter
The vacuum port in the carb itself is going to the Vacuum advance on the distributor.
HAC is removed because I'm at sea level and don't go above 4k feet.
Fuel cut solenoid connector was swapped over to the City Racer solenoid, Green wire harness side is going to the solenoid.
@FJ40Jim Air pump delete pulley, plugs, EGR plug all installed.
Swapped the filter housing over to a 3F carb hat with Japanese/FJ62 air filter box.
Initially I suspected a weak fuel pump with was able to move liquid but not string enough to push air and prime the carb. So I picked up a new one from @ToyotaMatt and replaced the Fuel pump, spacer, gaskets and fuel filter with OEM parts, also replaced the rubber fuel hoses with new hose. no change. Because the truck starts and runs no issue when I manually fill the carb through the sight glass, or pour fuel directly into the carb, I'm thinking possibly a restriction inside the carb itself not allowing it to fill?
Am I missing something here? I know it's got to be something totally stupid, this is a mechanical system. Also, If you see something I messed up please, speak up.
Edit: in these photos the old fuel cut solenoid is installed in the new carb. I removed it from the OEM, cleaned it, and tested it before installing it into the City Racer. I've since removed it and reinstalled the 1 wire one that came with it.
