*** Merci beaucoup. This 2nd girl is making us very happy. No one will mess
with my stock of old car parts, or my toolbox. In which I added a tailpipe
expander (2 1/8th to 3 1/4th) from Walker no later than last week. Who was
saying that a guy can't have too much tools ?

*** I don't have a 500$ bill under the hand right now, so I'll follow your
suggestion. A new baby is a good investment, if you know what I mean.

*** I indeed have a set of fuel pressure gauges here, I just wait for
Geraint or Brady to stop by and turn the key while I check the dials. They

*** I have 3 of these here, and they are behaving exactly the same. When put
in the freezer, they let a lot of air through their body. When the heating
element is hot enough, air passage is mostly restricted, but there is still
some "breathing" possible. Is this a correct behaviour ? Should they be
perfectly shut when hot? This part is way less expensive, around 85$.
