When I turn my key all the way, right before it engages the starter, it (fuel pump? Solenoid?) goes "click...click...click" about ten times, with diminishing frequency and stops. Again, this is before engaging the starter.

its most likely your fuel pump building pressure.

Have someone turn the key so you can track it down.
After pressure is built up in the fuel system, its quiets down.

That's what I thought. Just wondering of that's a "normal" fuel pump behavior as some are suggesting my current "fuel starvation" issue might be the pump. I still suspect carbs (gonna rebuild), or some kinda intake manifold leak thing.

fuel pump. it builds pressure for a few clicks then times out. UNLESS someone has bypassed and hot wired the pump to ign. seems to be common after 35 years and many hands of past owners

When you find it chances are it'll look something like this.

You might want to change over to the CB rotary.

Yeah...I believe it's hanging out right next to my fuel filter...under the battery area. What is a "CB rotary" and why would I want to switch over? Thanks in advance for the guidance.

Check it out here - http://www.cbperformance.com/catalog.asp?ProductID=577

It's much quieter and regulated at 3.5 psi. It will supply much more volume to your carbs at a constant pressure. Them tick tick jobs are too loud for me and drop off in pressure at higher flow.

Here's the facet style: http://www.racerpartswholesale.com/product...acet_Fuel_Pumps

As you can see it flows 15 gph at 1 psi where the rotary flows 30 gph at 3.5.

"Why"? Because the Facet pumps (or Empi, or whatever brand they are now) are junk. Were junk, are junk, and will always be junk. And they're not even cheap anymore, so they have NOTHING going for them. Except maybe the clicking .........

You will want to relocate the pump. Placing it closer to the tank will let it push the fuel instead of pulling it. It works better that way. Most place it under the tank where they can get at the filter through the access hole.

Having a less than stellar pump located so far from tank will contribute to fuel starvation issues.

(IMG:style_emoticons/default/popcorn[1].gif) There CAN BE a significant advantage to the CLICKING PUMP...If you pay attention....Sense, or time the clicks before it stops....IF IT KEEPS CLICKING you have a FUEL LEAK.,or a stuck and open float needle valve(now flooding your engine), or possably you are out of fuel (your guage broke),or ...can we think of some more advantages?...You do not hear it when the engine is running,so whats a little noise..use it as a tool.

Good point...makes sense. The clicking does stop if I wait until I hit the "ignition" with the key; it only clicks about 10 times I'm guessing.

Well said. They are only to be paired with Weber/Holley progressive carbs. (IMG:style_emoticons/default/smile.gif)

You got me there. I have never seen one like that. It looks in dire need of replacement though. I don't mess around with fuel system components. I've seen too many engine fire carnage pictures.

I agree with jmill. Relocate the NEW pump to the front along with a filter. Put the filter between the tank and pump. Consider a new line through the tunnel and all the way to the carb.

That's a new one. I don't know too many folks that defend the clicky pump. If you keep your fuel system maintained you don't have to worry about leaks or stuck floats. How can having 1 psi at 15 gph be better than 30 gph at a constant 3.5 psi? At high rpm, when you need the most fuel, your clicky pump can't hang. Fuel pressure with that thing goes up and down like a yo-yo. The major disadvantages outweight your perception of any advantage.

What access hole? Is there one in the pan below the tank?

Most place it under the tank where they can get at the filter through the access hole.
