I just bought a 99 CTD and it had an occasional stutter in it like it was running out of fuel. Checked lift pump pressure, zero.

The pump is still on the side of the engine and it was making no noise so I bought an Airtex E7153 that is a direct fit.

As my luck would have it, no pumping from this either. Checked for power, none. I have it connected to a switched 12v source now and it makes 18 psi.

Questions are:

Where does the stock connector get it's power from? What are the chances it's something easy. I've read it get power directly from the ECM.

How much current do one of those gerotor pumps draw? If I have to leave it wired as is I need to have it fused accordingly. It is currently fused at 10 amps which is running it OK but seems a little light to me.
