Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

Pull the vac line off the regulator right after you stop the engine. See if there is gas in the vac line if so the regulator is bad. If no gas is present it could be the check valve in the fuel pump letting the gas pressure leak down. Get a set of gauges and hook up to the fuel lines and check for pressure loss. You will have some loss but should hold steady for several hours. Another thing to try is turn the key on and off several times before trying to start this will charge the lines if this works every time you are losing fuel pressure. If you still have trouble when doing this I would look somewhere else besides the fuel system
