Re: [T3] Full flow to Go?

["iCBM email" <icbm@icbm.org>]

As Brian Fye can attest, I don't have such a problem so far.  I've been
driving my baby to work this whole week and am showing an idle pressure of
~10psi in the evening (rag back, windows down, T-shirt and shorts weather and
I'm a skinny dude).  In the morning it stays pretty much at 20psi @ idle
(mornings are rather chilly and I have the heat on).  Of course, I do have my
pre-cooler and fan and it has been running in the evening drive home.
However, there are only 7,900 miles on the engine.  We'll see how she does
this summer as I've decided to forgo this year's Gene Berg cruise and hit more
of the regional shows (Canada to southern Oregon).

As we've contemplated in the past, gauges and/or senders don't seem to be
extremely accurate so it's hard to say who's gauge is reading correctly.  I've
yet to get a red light after start-up...
