For me liftpen=2 does work as expected in the following example:

\listfiles
\documentclass{article}
\usepackage{pst-3dplot}
\begin{document}
\begin{pspicture}(-2,-2)(2,2.5)
   \pscustom[fillstyle=solid, fillcolor=lightgray]{
     \parametricplotThreeD(0,360){%
       t sin 2.24 mul t cos 2.24 mul 0%
     }
     \parametricplotThreeD[linecolor=gray,liftpen=2](360,0){%
       t sin  t cos 0%
     }
   }
\end{pspicture}
\end{document}
