I have a 2014 Corvette with a fueling problem.
The car-1g1yb3d75E5128503 when out of fuel will fill naturally until about 7-8 gallons are in. It then takes only a minimum flow rate until full. Dealer has replaced Anti-siphon grid,Charcoal cannister, and vent solenoid.
Car was from MacMulkin in New Hampshire thru Corvette Mike in California.
Dealer (Connell Chevrolet) has tried to fix but so far has no solution
No codes are apparent and the nagging problem is frustrating.

Sounds like the first tank is filling, but there is an obstruction in the crossover tube that will not allow fuel to flow over into the second tank. If the vent on the second tank is not working, that could create the back pressure. Did they check the float in the right tank to make sure it is working?
Don't think so... the fuel just flows through the crossover tube when the first tank gets full..until both tanks are full.
When the car is running, and the level drops in the left tank, the jet pump moves fuel from the right tank to the left tank until the right tank is empty.
As you can see, the fuel pumped from the driver side tank to the other tank is only enough to drive the siphon pump to move fuel to the driver side tank.
The engine only gets fuel from the left side tank (Line M), so the goal is to keep the left side full.
This is cool. Looks like its not a driven pump on the right side...not electric, motor, etc. The main electric pump bleeds some pressure to the venture pump on the right side to "siphon" flow to the left side.
Yeah, if he has tried nozzle position, etc. and that doesn't fix it sounds like its not getting fuel to the right tank.
