Man, if you don't replace known original/ used items like that, You WILL have problems. I could never figure out my 63 Dart gt... /6. I could push air ( my own hot air) from the pump input line and hear it bubble in the tank. Pulled the tank, cleaned it, everything. Except that damn hose... so YESSIR! And my 74 gave me FITS till I changed the hard line. Would idle, run, raise some cain, then just when IT wanted to, would die. Sometimes after half hour or more , sometimes enough for me to get out if the neighborhood. I bent them, and the brake lines by hand for my 66, got the inline tube line for the 74. And upgraded to the larger while there.
