Injector pump specs.

[kaiser2help]

Does anyone have specs for the LDS 465 1a injector pump? I am looking for the specs for the fuel screw and the droop screw. I know there must be reference somewere. For example fuel screw might be 1 1/2 turns out from being screwed all the way in. I know how to make the adjustments, I would just like to know if such info exhists. My engine lacks hard, and while I am mindful of its design and purpose this thing is a dog. If someone could elaborate, it would be a great help. All of the fuel system is current and in prime working order.

That kind of stuff is normally set on a pump stand. To get it correct, there are gauges and flow meters attached to the pump and calibration fluid is used. Fuel injection isn't like carburetion, No settings like turn it in 'till it runs bad then back it out.

There is a series of steps in the LDS trouble shooting manual that tells you how to adjust everything for the best amount of power. I would start there. It tests the motor installed in the truck.
