I suspect these pressure sensors may be positive pressure devices. The ones
you need must measure from -15 psi to plus 15psi and give 2.5v at 0PSI so
that the computer can see the vacuum.

If these will measure pressure both ways then the 15psi ones sound ideal.

The Weber Marelli pressure sensor from a Cosworth/Lancia Integrale/ Maserati
Biturbo will work well and it is available as a part and costs about $75.
This is a 25 PSI sensor though and wouldn't be as good as a 15 PSI one
