Car sputters

the old tank has a O-ring type of seal, on a 67 dart i used to drive it was cracked, and if we filled the tank it would leak and drip BAD for the first couple gallons. tried high-grade sealant, no good. gotta replace it.

also, i am having a similar stutter and die issue with my 62 lancer...since everything is rebuilt, replaced, or otherwise FIXED, i'm looking at loose spark plug wires being the primary culprit. that or the ignition coil (recently replaced) or the ignition module, which was also replaced last summer. my car is converted to electronic ignition, still trying to figure out if that's a good thing or not. :)
