My recently acquired 914 seems to lose fuel pressure after running for a while. Here is what I know for sure. I have pulled out the screen in the tank and have installed a carter fuel pump and all new lines including through the tunnel and under the tank. The car is a 76 with 44IDF carbs and a holley fuel pressure regulator with a guage installed after the regulator. When cold the fuel pressure pumps right up to 3-3 1/2 psi. Letting the car run in the garage for 20-30 minutes the pressure guage drops to 0. I have installed 2 different pump and the problem persists. Any ideas.

Tank does have the expansion tank in place and blowing into the hoses it does appear to be ventilated properly and have new filter installed. Fuel pressure regulator operates properly when fuel pressure is present (cold). Last drive emptied the carbs and had to allow carbs to refill to limp it back home.
