PZEV "controversy"

Thu Jun 28 08:19:01 PDT 2012

SCORE!    LOL

Glad my cuiosity didn't creat a torsen thread.... nor that my limited
understanding of the systems were off base.  =)

As for fuel lines, there *needs* to be some flex, at least at the engine
bay.  They can have (metal) braided lines for flex, but there is still
rubber/plastic inside, so I just don't see how 100% solid metal lines would
work in ANY car.  As for selaed tanks, you can seal things with a gasket,
so there's no reason it can't have a cover.  Besides, the lines and wires
have to enter somehow, so by definition there is a sealing connection,
overmolded, or seal, or gasket... but there still is a penetration
(several) into the tank.  PZEV just requires that the system be
(paraphrasing) "airtight" for 15 years or 150,000 miles, so it might make
sense if the gaskets or sealing mechanism were more robust today.  But
again, what could it add?  A few dollars to the tank/gasket system (at
most)?  ECU tuning is "free," so the real cost would be a more efficient
catalytic converter, some of which can be solved by putting it closer to
the engine for faster "light off."

It just makes sense that commonality would reign in this regard, as EVAP is
still mandatory (in all 50 states) and so many cars are built without a
dealership necessarily in place.  Window Stickers get put in "at port," and
even then dealers trade before the cars are trucked to them, let alone
after.

Thanks for checking, Cody.  I do appreciate it!!!
