I just bought a new mechanical pump. I checked the one on the truck with an not-ideal setup and only got about 1.5 psi and it took about 45 seconds instead of 30 to fill a pint. Could be accurate, could be the wonky hook-up. ('Universal' fitting in the vacuum/pressure gauge from the parts store... sorta shoved into the filter nut...)

$20. We'll put a new one on.

I'll also check for any blocked lines while at it.

The filter in the inlet port of the Quadrajet is what I replaced. That's the only filter with the exception of the sock in the tank. The one i pulled was dark red/brown and hard... so I'm sure it contributed. It took a while for the new one to show up, and since I installed it I haven't been able to replicate the bog-down.

Trying everything before I decide I must go to the tank. I'm a true 'shade tree' mechanic without a garage. Taking the tank down and replacing the sending unit may be something I pay to have done....

Thanks fellas. Feels like we're on the right track.
