My original gas lines were leaking. I was lucky to find them before a fire broke out. The gas ran down the frame towards the engine and I assume sooner or later it could have ended in a disaster! Anyway, I replaced the line with ones that I bought at Auto Zone and I have lived happly ever after, until now. I am wondering if they really do require special lines that were manufactured by a Delorean supplier. The presure cannot be that great in the system, but in any case if it requires a $10.00 part I am not adverse to spending the money to aquire it. I am just wondering why it would require special gas lines. Scot Stern 6452
