"1987 Alpha one/ 5.7. I recen
"1987 Alpha one/ 5.7. I recently replaced the old q-jet with remanufactured unit, and it runs much better. However, it was still intermittently crapping out. It would always restart, and run fine for awhile, so I thought I'd look in the fuel tank. I pulled it out and drained the contents into a bucket. There was some amount of debris, and probably between a pint and a quart of water at the bottom. I cleaned the tank, reinstalled it, and took it out for a test. It ran fine for the hour I had it out.
The question is, how much water has to be in a fuel tank before the water-separating fuel filter can no longer do it's job? I have no idea how that thing works, but it seems to me that if the fuel pump is sucking nothing but water off the bottom of the tank, the filter's not going to be able to filter any fuel to the motor. Did I just answer my own question?"
