[s-cars] (no subject)

Thanks Mike... ...You own two huh?  Glutton!

The reason I mentioned the 1/2 of a tank was to avoid the "Are you sure you
have gas in the tank?" question.  ;-)

Have a great weekend!

Brooke: You said it happens with 1/2 tank?

Less gas in the tank, the more work the pump does just lifting the
fuel. Less power remaining to pressurize.

So maybe it's a weak pump or a clogged filter. I don't think there
will be a connection between tank level and FPR function.

But I don't know much (and I can't be getting smarter since I own 2 of
these cars now). Listen to what the other guys say. I'm writing this
only because I wasn't sure that anybody noticed the 1/2 tank
reference.
