does anyone know the difference between holley's commander injection kits that seem to replace the carb and edelbrok's kits which replace the intake manifold and carb? are they both true fuel injection kits? which will work better if there is a difference in them? i also just bought a auto meter fuel gauge and i'm not getting the gauge to register the fuel level i know everything is wired right, any troubleshooting tips?

The holley kit is more like throttle body ( early style fuel injection) and the edlebrock is more like current fuel injection. I would think that they both would work good but I would have to go with the edlebrock (cannot stand holly). As far as the gauge I have never messed with one, I do not know what the problem is if it is wired up correctly.

I know a guy that put a Holley Pro-jection on his Mustang. He couldn't believe the differance it made. They are extremely tunable and work well. I don't know about the Edelbrock, but it is a reputable company so it can't be all bad. Just depends on what you want to do with it.

I have no experience with either type of injection,
but...
What is the ohm range for the autometer gauge?
Does your fuel sender register;
75 ohms at empty and 10 ohms full?
Autometer has at least 6 ohm ranges available in their gauges, you must match the sender to the gauge...
Sorry if I am just spouting info that you already know,
Does the gauge read "full" if you ground the wire from the sender plug to the frame?
Do you get a varying voltage reading at the sender plug using a voltmeter?
If both of these check out, you may have to check the sending units range by pulling it out of the tank, and using the voltmeter on it.

as far as the gauge goes it is grounded and reads empty. i'm pretty sure the ohms on the gauge is 73-12 ohm which is what jegs says works with pre-89 ford/chrysler. i didnt check the voltage on on positive nut of the gauge. should the truck be running when i do that or just have power to it?
