Re: Spider gas cap question- does it need a seal & Spuica pump question

["Jason Hagen" <hagen_jason1@domain.elided>]

Thanks for your reply.  There seems to be different gas cap types on these 
vehicles.  I bought both a '73 and a '74 Spider, both were original, and 
both had the thread on gas caps, not bayonet.  The strange thing is one gas 
cap was larger in diameter than the other- they actually changed the size 
between the years which also meant a change to the gas tank filler intake 
diameter.  Yes, my '73 and '74 (ripped apart for scraps) had different gas 
tanks!
