Fuel Pump Problems?

1991 Accord - Does not start when it is hot out. Originally thought it was a bad fuel gauge. But only ran into problem during middle part of the day, or immediately after shutting off the engine. Have read somewhere that the terminals on the fuel pump, when they are corroded, can cause this problem. Where is the fuel pump located on this car, so that I can take a look at it? Any other ideas would also be appreciated.
