90 to 91 info and differences

I just picked up my 2nd ZR-1, a 91 from the original owner (friend of a client) w/ 90k and never disturbed as far as I was told and it looks to be all original. My car is a 90 w/ 30K and I love it!!
I have a couple questions for you more knowledgable owners:

1) Do 91s have the tank vapor can / filter under left frt. hood area?
2) Are the brake systems the same 90 & 91? The 91 seems to stop better with a firmer pedal.
3) Are there any other differences worth mentioning?

Any input will be appreciated as I decide to keep one or both of them if I can! One of these cars will be @ BG in May , anyone going up from Florida please contact soon. See you there.

No it got moved to the passenger side of the fuel tank.

It's the same. Try a fluid flush.

Nothing major.

There are some minor differences in the plenum vacuum hose routing. As Jeff said, nothing major. Just be certain to check if it's MY specific when you start with the vac stuff.
