I’m in the process of a DIY EFI conversion on a V12 E-type. I got some rebuilt 19lb EV6 injectors (Bosch 0280155702) pretty cheap thinking it would fit the XJS manifold I sourced for this project, but it doesn’t seem to be a perfect fit.
The O-ring recess in the manifold only appears to be 5mm deep, so the O-ring retainer seems to interfere with the O-ring seating all the way.
Can I just remove these things? Since there is already a machined step from 10mm to ~13.7mm, there is no way the 14mm O-ring would slip into engine.
Some rough measurements of the injector boss in the manifold;
| <--16.7mm--> | 2.5mm - - | | 5mm | <--13.7mm--> | - - | | | <--10mm--> | 6.35mm | | ==== ====
O-ring crush appears to be about 1mm (~0.040 in). Which is a tight fit but should be fine.
Found a few references to people running without the retainers on E38 BMWs without issue.
What do you folks think?
I’m completely new to EFI and learning in the process.
