I kept the "failed" pump I replaced in Dec. Tested on the bench, it works fine... head bang

Like you said earlier Rusty.


Provide a reliable and over-capacity power supply to the lift pump

The pump was not getting enough JUICE!

See my last year's post on the Turd Fairy.

I started getting a vibration in the rear about a year ago.

So I balanced the tires. Still there, but it came and went, and was barely noticeable, so I lived with it.

It got worse, so I had the tires re-balanced. Still there.

Had the tires balanced again. Still there. A couple of months ago I noticed unsual wear on the right rears covering about 60° in the same place on both tires, and one wheel had about 3/16" lateral runout, so I replaced it and the tires and put in balance beads on all four rears. Still there.

The shocks were weak, so I replaced them. Still there

I had the left rears pulled, and noticed a small stone had imbedded into one of tire's the grooves and had severed at least one belt and damaged a second or third. Replaced the tires. Very little change.

Earlier this week, I replaced the water pump, because there was dripping from the weep hole; I was none too pleased, as the engine had <30K miles on it. Removing the fan to get to the pump, I saw notches in the blades where they had rubbed against the steel shroud. At rest, there's at least 5/8" clearance.

This could be caused only by bad motor mounts, so I checked them, and the left was toast, and the right, none too good.

I had the motor mounts replaced, and the problem seems cured; apparently driving at certain speeds started a sympathetic vibration in the engine, and it was bouncing.

I don't know if the problem's really fixed (I've thought that before), but it seems to be.

EDIT: I added link to a source for HD motor mounts in this thread.

I finished the new harness for the lift pump today; one 3" stretch of the old had 3 butt connectors in a row. This new one is soldered and heat shrunk, and I made taps for running a relay and a new ground, if needed. The tap can also be used to jury-rig a temp connection. Mechanic Tooling Along

I also fitted spade terminals at all connections and modified the pump bracket, so if I do have to replace the pump again, it's a 10 minute job instead of 45 minutes.

For fun, I tested the kickin and dropout voltages on the spare high-quality and generic lift pumps. The former started at 4.85VDC, the latter at 10.45VDC. Quite a difference - and the High-quality pump was much more assertive.
