1994 B230FD engine vs 1993 B230F ? 900

I am considering the purchase of a 1994 940 wagon (89K miles) with B230FD engine. Compared to the B230F on my 1993 940 wagon, the FD has Bosch FI instead of Regina. It also has some additional plumbing into the exhaust ports. Is the plumbing part of an air injection system ? Are there any maintenance issues with it ?

Any significant differences between Bosch and Regina FI that affect reliability ? The ones I know about are:

Bosch uses Air Mass Meter, Regina uses pressure and temperature sensors

Bosch has two fuel pumps (in tank and external), Regina has one fuel pump (in tank)

Should the FD engine deliver similar gas mileage to earlier engines ? The owner claims 23-1/2 on 20 mile trips, 27 on long highway trips. My 1993 940 wagon gets about 25 /28. My 1991 740 wagon gets about 27 / 29.

Thanks,

Mike
