78 RC with a 360, it sat for a few years and the end of last year I started throwing $ to start driving it again. Bought a new 600 cfm Summit Racing street strip carb. I was having issues with not getting enough fuel to the carb so I bought a new fuel pump and it seemed to be ok for a week then it died one day. I got it going again and pulled off the pump and installed a new electric carb fuel pump (4 psi) max was still having issues. I dropped the tank and saw the line at the top of the tank was split and sucking in air. Fixed that and it seems to be ok. I still have the electric pump on and now it idles fine parked about 800-900 rpm but when I put it in gear ithe rpm drops low and sometimes dies. What could be causing this to happen? Does the electric fuel pump not supply enough fuel? Before I put the electric pump on and fixed the line on the tank it seemed to idle better, when it wouldnt run out of fuel.
