Late note: Sorry, it appears that this works for the '78 & later, but not '75-'77.

From what I can see there's barely enough room to get a wrench in there

Do a Mooser said. To test, jack the rear up a bit and with the line loose at the fuel pump you should get a lot of gas flowing thru the line once you get it started with a little syphon action.
Go from there.

After that, test your fuel pump. Start the car and let it run for a minute to fill the fuel bowl. Shut it off and disconnect the fuel line, attach a rubber hose long enough to slip into a 2 liter bottle. Restart the engine and let it run for 10 seconds or so. You should have about a pint of gas in the two liter bottle if the pump is working properly.

I just had a thought, do you think that the alternator being bad would have anything to do with the problem? I've see the volt gauge dropping below 13 quite often in the past few days, just about the same amount of time this problem has gotten worse (It used to be about 70mph, now its 40)

If the lines turnout to be clear, you might have worn out cam lobe that the mechical fuel pump operates from. The pump most likely can keep up at lower demand. But when the engine is under a high fuel demand the pump can not keep up. If your engine has high hard miles with the original cam or fuel pump one or the other might be it. The quick way is go to a electric pump. To check the lobe and pump push rod means removing the pump and use a dial indiactor to check the stoke.

No it most like is not but it is worth it looking into.Break out the volt meter. First check the battery w/ the key off.Should be 12v. Strart the car volts, should go up. Race the engine around 2000rpm for short burst. See if it changes. Ignition systems uses only 9volts, but something else could be draining. A loose ground, bad connection, or a loose belt.

WOW! Alot of good advice. I bet I have had all of the problems that you guys told him to check for over the years(thank goodness not all at once). The first time I had a blocked muffler (because the cat fell apart ) I was stumped, never even heard of it before that. I did just have to change my tank meter because it was clogged up, reducing fuel from getting to the carb.
