Not very easy doing a return rate test on the lb7's tho unless you do 4 at a time
Hey guy i am new to the forum and was looking to get a efi live for my lb7s and one of my friends told me i should talk to THEFERMANATOR to get a efi live. i am sorry if i am posting in the wrong place i will learn how to use this forum soon..
If you can let me know on how to get one let me know.
Thanks
Seems like you could rig something up to test the injector banks but I have no idea how you would test individual injectors on the LB7 since the return lines are under the valve cover. Sounds like you'd need some 100ml graduated cylinders and then get creative on how to attach the return lines (doesn't need to be pretty). I know I've done it on LLY+ trucks without the KM tool ($$$) but I would think you could at least get a return per bank on the LB7 (even a total injector return would be ok to indicate an issue......8 injectors returning less than 40 ml for 15 secs cranking). Maybe I'm missing something though.
Here's the procedure for it:

You should be able to isolate the return from the injection pump too:

The OP may also want to replace one of the rubber lines after the filter head with a temp clear vinyl hose to make sure you have good fuel supply (ie no air bubbles and hose doesn't collapse).
