How to Prime a Grease Gun
Grease guns are an essential part of any mechanical workshop or facility. Grease guns make it easy to distribute lubrication to the moving parts of all types of machines. In a mechanics workshop, a grease gun might be used to apply grease to ball joints, U-joints in the drive shaft, tie rod ends or wheel bearings. When using a grease gun, you will want to have an even distribution of grease with each pump of the guns handle. This can be achieved by priming the grease gun before placing the nozzle of the gun next to the equipment.
Instructions

Pull the T-handle and rod out of the grease gun. Push down on the handle slightly to lock it into the open position. There is a small groove into which the handle fits to hold it open while you load the gun with grease.
2Unscrew the metal cylinder inside the grease gun and pull the empty grease cartridge out. The cylinder screws into the gun near the nozzle.
3Pull the rubber or plastic cap off one end of your new grease tube. Pull the metal tab off the other end. Slide the new grease tube into the metal cylinder so that the metal-tab end faces down toward the dispensing nozzle. Screw the cylinder back into place in the grease gun.
4Unlock the T-handle and rod and push it in and out of the new grease tube two or three times. This will create a channel to push air out of the back of the tube and allow grease to flow.
5Squeeze the handle of the gun several times until grease begins to flow consistently through the dispensing nozzle. You should do this over a trash can or a shop rag to avoid dispensing grease onto your floor or work surface.
6Unscrew the bleed screw at the top of your grease gun and pump the handle a few times to open up the flow of your grease gun. Tighten the screw once the grease is dispensing freely. You usually wont have to perform this step unless the grease in your new tube is cold and heavy.
7Pull the T-handle and rod back out and pump it in and out a few times if your grease gun loses its prime while you are applying grease.

How to Prime a Fuel Filter Water Seperator
Priming a diesel fuel system--including a water separator--removes air from your vehicles fuel lines. When air enters your fuel lines, the fuel system becomes air bound and fuel will not travel from the fuel tank to the fuel delivery system of your vehicle. After cleaning or installing a new water separator, you will need to remove the air from the system to allow your vehicle to perform correctly.
Instructions
- 1
Turn the petcock located on the bottom of the fuel filter/water separator counterclockwise.
2Crank the engine by inserting the key into the ignition. Allow the engine to crank for 30 seconds. Check the fuel filter/water separator for air. If no air remains, turn the petcock clockwise to close the air way. Close the petcock and continue if air remains in the fuel line after cranking the engine.
3Locate the hand priming bulb in the vehicles engine compartment. Repeatedly press and release the priming bulb until you see air bubbles moving toward the air release valve.
4Press in on the priming bulb. Turn the air release valve counterclockwise. Keep your hand on the valve handle until fuel flows from the valve. Close the valve quickly while maintaining pressure on the priming bulb.
5Wipe spilled fuel from the engine compartment with a clean rag.
