    fuel presurs

    I HAVE A 1970 NOVA SS 671BDS 355CI WITH 2 HOLLEY 750 DP CARBS WITH HOLLEY BLUE PUMP AND REG USING #8 FUEL LINE FROM CELL TO REG. CELL IS VENTED AND CLEAN . PROBLEM IS I START WITH 7PSI OF FUEL PRESURE AND AFTER 15 MINUTES OF DRIVING FUEL PRESURE FALLS TO NEAR ZERO. FUEL LINES ARE COOL BUT BLOWER AND REGULATOR IS VERY HOT TO THE TOUCH DUE TO LEAN CONDITION AND ALSO ENGINE TEMP HOT. LET SET 30 MINUTES AND PSI STARTS TO INCREASE AGAIN
