This is a vague question. Ill do my best to answer in a few different ways and maybe i will hit on your application.
First off some of the corvette 350s and marine 350s had the water pump that spund backwards so the impeller in the pump is different that the standard 350 pump and you CAN NOT see the difference from the outside.
MOST IMPORTANT!! disconnect battery cables first thing then drain coolant. MAKE SURE ENGINE IS COOLED DOWN. HOT COOLANT CAN BURN SEVERELY!!
STEP 1 On early 350s (with V-belt) you need to loosen tensoner bolt on alternator (top) and stationary bolt on alternator (bottom). push alternator forward to loosen belt and remove it.
On later 350s have serpentine belt. If motor has serpentine belt locate belt tesioner and use tesioner to loosen belt and remove belt. (pay attention to how belt "snakes" through the pullies because you will need to reinstall it the same way).
IF Power Steering PUMP BELT IS INVOLVED. loosten tesioners on powersteering pump and remove the belt. there are many styles of mounting for power steering pumps so you will have to look it over to figure out which way to get the belt off. If powersteerin pump bolts to water pump remove bolts and move pump out of the way.then go to STEP 1.
Remove fan by taking out 4 bolts in front. if vehicle has electric fans disreguard this step. If fan shroud is in the way remove it.
if smog pump bolts to water pump remove bolts and move smog pump out of the way.
remove lower radiato hose (catch coolant in container and dispose of properly)
remove hose that goes from water pump to intake manifold.
the standard Chevy 350 water pump is held on by four bolts. the alternator brackets may bolt to water pump in one form or another. they need to be removed as well. once all accessories connected to water pump have been removed pull four 9/16 head bolts out of pump and pry it off with small bar.
Due to the lack of information in the question the answers here cover a broad base. with a little thought and looking you should be able to peck your way through a water pump removal easily with this bit of answers. Just pay attention and take your time.

NO.
Remove the water return hose from your 1996 Chevrolet water pump. Remove the water pump belt. Remove the water pump retaining bolts. Reverse the process to install the new water pump.
the water pump seal is worn out you need a new water pump
it flows north
take the fuel tank out of the vehicle. the pump is inside of the tank.
That would be a long shaft water pump.
water pump will sit on engine with lower radiator hose inlet to the left, make sure you dont have a "long water pump", it wont work, 350 is a "short water pump"
Take the old one with you.
NO it will not work.
In a 1996 350 LT1 Chevy model, the water pump pumps water into the heads directly through?æa hose. The water does not flow through the?æinternal water jacket.
To loosen:counter-clockwise.
