There is nothing worse than a problem that cant be figured out. Im frustrated just reading this thread...but I dont think hanging a holley red under the truck is the answer and I wouldnt trust those pumps on a tow vehicle. Obviously if its loosing pressure there is something that is causing it. Is it possible that the gas cap isnt vented and or the vent is plugged? Try removing the gas cap and see if the pressure still drops. I had this problem on my station wagon and it was the gas cap not allowing any air by. It was actually sucking the tank and the lines inside out. I could do a burnout.....stop and lanch it. By the time I got into second it would loose all fuel pressure and run out of gas. Let it sit for 5 minutes and it would fire right back up and run perfect. Just a thought. Any rubber line in the fuel system that is old should be changed as well that way there is no chance that the pump can colapse it.
