ok, i knew i'd seen the 912 L jet somewhere.
it was on mr. bowlsby's fantastic website.
link to a a little tech publication he has there.
i think originally the booklet might have been made by someone on the 912 registry.
https://bowlsby.net/914/Classic/zTN_Man08.pdfanother one from mr. b's website covering the smog pump on the 75/76 914 Djet.
a factory tech publication that goes right through changes for 75 MY and shows the smog pump. imagine smog pump on 912E fairly similar.
https://bowlsby.net/914/Classic/zMan_1975_S...iningManual.pdfcan't help much more than that.
912 E is not a car that ever came to australia.
pretty rare car for even for the USA?
looks like a 912 E had both exhaust gas recirculation and a smog pump.
double the trouble.
looking at all those engine photos posted above i can recognize a lot of the L jet components that are also on our 1.8s. just in slightly different spots sometimes compared to the 914. an interesting mish mash of parts, some from 2.0 D jet some from or similar to 1.8 L jet.
i imagine the fuel rails and fuel circuit plumbing is close if not identical to a 1.8 L jet.
use a 1,8 L jet fuel hose diagram for guidance? injectors are different, but not by much, just a different flow rate. there are diagrams posted around the web for 1.8 fuel line layout.
the L jet manual link to mr. b's website has a vac hose diagram in it for a 912 E.
good luck.
ps you could use the 914 factory manual, section on fuel injection to help you out with some of the L jet components. how to get them on and off etc. most of that stuff will be the same. aux air valves, decel valves etc etc.
here is a link to the 914 factory manuals. all you need is the section (volume) on fuel injection. download that bit. L jet stuff is in there.
