I changed over and added a "boost pump". Too many close calls like yours!

I also had a fuel starvation engine "hiccup" probably caused by a cracked main fuel filler cap.

Sam and gang,
I have to admit, thinking that I scared the hell out of myself because I
didn't tighten the gas cap properly is a bit annoying but at this point,
this line of thinking is making the most sense. If you or anyone has a way
to test this I would appreciate it.
Also, any opinions on a boost pump to give a bit more margin would be
I still may have some engine problems that I want to get to, but I feel sure
that my excitement was fuel related.
Note....I really don't want to do a repeat performance. I'm sure the tower
would appreciate it too.
This phenomena of the low pressure air leaking into the fuel system is well
documented. In fact, that was my first thought when I read your e-mail.
Naturally all the gascolator foes come out of the woodwork, but if you have
a leaky gas cap you will have trouble.
It happened to me, to Art Jewett, and to others. I made a mention of it on
my modifications page: http://home.mchsi.com/~shoskins/modifications.html
