farad is the unit for capacitance in SI system. If one volt is developed as one coulomb charge is placed then capacitance has to be one farad. But one farad is enormous large one so practically speaking we use only micro farad, nano farad and pico farad. They are respectively 10-6 F, 10-9 F and 10-12 F
about 500 uF

micro farad
Since the total capacitance for capacitors in parallel is the sum of the individual capacitances. I'm sure that you can work it out for yourself!
It is usually 80-100 UF(micro farad)
Capacitors are built to different specifications depending on application. The higher the capacitance the more charge the capacitor can store.The capacity to store electric charge, when a voltage is applied. Measured in Farad = Coulomb/Volt. In other words, if for every volt applied the capacitor stores 1 coulomb of charge, it would have a capacitance of 1 farad. In practice this is a huge unit, and the capacitance is usually expressed in micro-, nano-, or even pico-Farad.

You can't. Look at the markings, they usually say what it's good for.
have you checked your computer? If your pump stays on when you first turn the ignition; without turning on the engine, the pump usually turns off after a few seconds. If your pump stays on then you can suspect the computer. Remove the computer. Remove the two Torx screws and open up the box. Then look for three capacitors. Two will be 47 micro farad 16 volt and the other will be a 10 micro farad 63 volt. If they look bloated or like they are leaking some black stuff or if the leads are detached from the PC board; replace them. You can get the capacitors at the radio shack. The trick will be that you have to buy two 4.7 micro farad capacitors in the place of the 10 micro farad capacitor and wire them in a parallel configuration. The reason for this is that they do not sell a 10 micro farad with the VOLTAGE rating that is required (63 volts). This is the only capacitor that requires a 63 volt rating. MAKE SURE THAT YOU BUY "POLARIZED" CAPACITORS. Hope this helps
A Farad is the electrical unit of capacitance. Many commonly used capacitors (also known as condensors) are measured in micro-Farads (μF). A micro-Farad is one millionth of a Farad. To convert from micro-Farads to Farads, divide the micro-Farad value by one million. 2 micro-farads = 0.000002 Farads.

A microfarad measures electrical capacitance. A farad can be defined as the charge in coulombs, which is 1 ampere per second, that a capacitor will accept for the potential across it to charge one volt. A microfarad is equal to one millionth of a farad.
