I'm contemplating moving into the world of 700s. Is there any intrinsic advantage or disadvantage in having the Bosch fuel delivery system vs. the Rex-Regina? Is one clearly better than the other?

Thanks in advance.

We've found the Regina system pretty reliable on the 91 740 with one exception...the single in tank fuel pump. Have lost count on how many we're been through although 5 sounds reasonable. From what I read from guys who have torn down failed ones, the pump is of questionable quality at best. I believe it is made by GM, not Bosch. As the other respondent said, the system does not use the expensive AMM.

I guess, if you want a 1990-1993, you will ultimately end up with a Regina system anyway. There are some Bosch cars but they're the 50-stat variety so they aren't as common.

The Bosch system is... well, Bosch. Predictable, etc.

Regina parts are a little more expensive, but there is no airflow meter (MAP sensor instead) and the computers are pretty reliable.
