I have a Vision Microsystem VMS 1000 engine-fuel management system which has now been in service for ten years on my fuel-injected 320. I'm more than satisfied with it's performance; however, in spite of a 'by the book' installation of the fuel pressure transducer, I've had three fail in the past ten years. JP Instruments (who purchased Vision Microsystems several years ago) now wants an outrageous $400 for a replacement transducer. They keep the manufacterer/model a secret in order to support their price, but some research revealed it to be a Honeywell 'MediaMate' model MM050PG1HA http://sensing.honeywell.com/index.cfm/ci_id/142358/la_id/1/document/1/re_id/0 It has a 0-50mVDC output over its 0-50 psi range. I contacted Honeywell and learned that their suggested retail price is $268.

I did a more research and found a lower cost and, I believe, superior replacement. It's a Measurement Specialties MSP 340 model M3421-000006-100PG

http://www.meas-spec.com/product/t_product.aspx?id=5115 It has a 0-100mVDC output over its 0-100 psi range. It's a direct replacement, except that the green and white output wires have to be reversed.
