I can try it but I don't have a 'hard [when] hot' start problem. It's 'no start' and it's electrical I think. But to test my theory, if I take off the fuel line before the injectors, and there is gas and pressure, it is not the check valve right? And if I jump the pump relay or fuse and gas is flowing that means there are no clogs.

I will be extremely careful to direct all the extra gas into a bottle and keep the garage ventilated.
