Actually it's identical to contemporary B28F. Same CPR. Same metering head. Same Lambda Sond. Of course fuel/air mixture unit and intake manifold are identical. I have a whole B28 top end from a 1990 760. Only difference is the CPR. Are very slight differences between B27 and B28 (Series 004 CPR vs Series 066 for example), but that's all (single piece fuel/air mixture unit casting has absolutely no effect on mechanic's ability to tune). DMC was buying these things on pallets and simply dropping them into production automobiles. Was the only way to qualify for US emissions on such short notice. They did no engine work themselves (not even research & development). You may well run into a Volvo repairman who's never seen a PRV, but that merely denotes the engine's North American paucity compared to the 4 cylinder unit, not some DeLo difference.

It is nearly bullet proof, remember their are components that are Not Volvo, It is a delorean!

The fuel system is something you don't want to leave inexperience mechanic trying to learn on your car.
