Fuel pump check valve and other sundry items

[Matt Suffern]

I little OT, but the weirdest thing I've ever had leave a mark on one
of my cars' paint was a miniature pumpkin.  I was getting our son out
of the back of our old Volvo 944T one evening, and put the pumpkin on
the roof.  We rushed inside and I forgot about it.  Came out the next
morning to find it had left a squiggly donut-shaped mark on the roof.
I didn't try really REALLY hard to get it out, but the polishing
compound didn't really affect it all that much.

So, watch out for those pumpkins!
