Do you mean vacuum pump? If so you probably need to change ALL vacuum hoses. With the new pump comes new vacuum pressures, old hoses will probably be sucked off their pipe nipples or small cracks turn into large ones, one or both of the above will cause severe rough idle and running along with much power loss and fuel mileage will ****. If you have the original service manual on the truck and engine (I am assuming you have the 4.2L straight 6- 2F) it has a vacuum hose routing view in it. good luck

I can run the motor at any rpm for several minutes before engine wants to choke out, runs rough. If I squeeze the ball 5 to 10 times , it will run fine for several minutes before acting up again.

New fuel pump and fuel lines.. Ran like a champ for day... BUT
Are you saying you think it is getting too much fuel, or not enough ?
Could be the choke or something inside the carb.

OK. Nothing to do with water pump.
Recommend checking your IAC (Idle Air Control) circuit. This allows air to bypass the throttle body while idling, at stop sign, etc.

Sounds like a transmission problem. Change the transmission filter and fluid and make sure it is topped off to the proper level. Have the transmission checked out to ensure there isn't a problem in the torque converter.

1995 Chevy Astro rough idle after choke goes off and engine is at full operating temperature, also no check engine light.
Inspect/replace air filter.
Fill the gas tank to above 3/4 and add Lucas FUELSYSTEM CLEANER.
Ran on the highway for 10+ miles.

Monitor is the rough idle condition is getting worst on below 1/4 tank.
Change fuel filter and check fuel pressure.
Most failing/weak fuel pump will not work well below 1/4 tank mark.
It will fail in a HOT DAY.

Have you checked the choke to see if it is operating properly? If it's not coming off that could cause it too run very poorly.
