Haven't had much luck with the electric pumps lasting. Are the mechanical pumps reliable?
Is there a spacer required on a 76, or just a gasket?

Mechanical fuel pump?

1 change every 10-15 years reliable enough? Heck yeah!
No spacers required pre-79 IIRC.

In contrast.. I've run the same electric pump for 8+ yrs and no problem...
In contrast, the mechanical fuel pump in my FJ45 is 40 years old. No problem.
i just replaced the oe fule pump after 43 years of use. And got an oe one to take its place.

What is the best way to test them?
My mech pump likes to leave me hanging when I go up in altitude - from ~5k' to ~9k'

Ain't the fuel pump.
In another contrast... a local '59 / FJ25 has the original mechanical pump and is still tooling around 
I replaced my mechanical pump after a mere 30 years of service. It was leaking a little fuel into the crankcase. Turns out I really didn't need to replace it -- I could have just installed a new diaphragm in the pump because everything else was fine.

I'll try mechanical. I already have one but didn't install due to the spacer question. I gathered the later model answer per parts listing but didn't want to break anything. Thanks
I just had one go bad on the trail yesterday.
Darn pieces of junk - only lasted 32 years.
I'm going to stick with the mechanical, and rig up a "pre-wired" electric spare for emergencies.
Where's the best place to get an OEM replacement? NAPA, etc. has mechanical pumps, but they are generic types....

Your carb is tuned at a lower altitude than what it needs at 8000ft. It is probably running rich at altitude and that could be what your poor running condition is.
The air at 8000ft is less dense than at sea level. So at sea level your carb mix air/fuel is good and you get good pick up. But at 8000ft your air is thinner so the mix is too much fuel not enough oxygen.
