[DML] Re: DeLo K Jetronic vs Volvo

["content22207" <brobertson@xxxxxxxxxxxx>]

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.

have they ever worked on deloeran's specifically the fuel system?
