This may be a good example of a message I gould email and not clutter
the list. But I can't.
No, it is not the fuel pump. It is totally dependent on fuel line
temp. That is why it took so long to figure out. After a hard day
at the autocross and a drive home through heavy traffic on a hot
afternoon, there it is again! Open the hood, the filter is empty.
Just walk away. Half hour later, come back and look at it and there
is fuel in the filter. The vapor condensed and the fuel siphoned up.
The heck of it is, my RV-mechanic-I-never-drive-anything-but-Chevys
brother-in-law told me what was wrong the first day and I didn't
believe him. I am trying regular leaded gas now, and not using any
boosters. I used to be get 104 racing gas up the street for $1.80, but
its not available anymore. The same company sells 108, but only way
over in MInneapolis and its about $3.50. R&T or C&D just had a blurb
that racing fuel is getting popular around the country and that one of
the advantages is low vapor pressure. Makes for hard starting and
poor winter performance, but won't vapor lock. Sounds good to me, but
avialability here is poor.
