Difference between fuel injectors
 

Can someone tell me the difference between these fuel injectors?

0 280 150 015

0 280 150 024

0 280 150 036

My 280se 4.5 has 7 x 0280150036
and one of the 0280150024 installed.
Both types are blue top injectors.

In the "1972 Mercedes table book" I find
the 0280150015 as the original Bosch partnumber for the car.

M 117.983
M 117.986

0 280 150 015 superseded by 0 280 150 043 ,used till 03.1975 (MB 000 078 18 23)

0 280 150 024=0 280 150 036 (used from 04.1975 till end 1975) (MB 000 078 34 23)

on the EPC,the old type MB 000 078 18 23 is substituted by 000 078 34 23+some ring A1160780473,so you might have the correct ones....some upgraded ones...)

That`s what I can help with...
Good luck!

Can't tell you for sure about the 015's, I don't have a set of those, but I believe those are the yellow ones on the 3.5, which flow the same as the 4.5's from all the research I was ever able to find.
The 024 and the 036 flow identically. The 024's were used on some Volvo if memory serves, and were more common so often used to replace leaking 036's. The difference is that the 024 doesn't come with the hose attached, it's a 2-clamp style; the 036 (that hasn't been re-hosed without a crimp tool) comes with the hose attached to it.
