It's a 1986, 305, Quadrajet, got it last May. (pretty clean for a WI car) Gave it all kinds of love... plugs,wires cap,rotor,rear springs,shocks, battery,exc.... was running weird...discovered cat was plugged, cut that off and temp. fix w/flex tube. Now having issues trying to get fuel filter to let loose. What engine do you have??? Quadrajet??? Hoping mine will be a driver real soon. As soon as I can get that fuel filter off, lookin at some new exhaust. Know what size fuel line is???(at filter) Metric??? 5/8 just the tiniest bit loose, I really need to ream on it, but don't want to strip it.
