First you need to buy the new filter and with this you must choose how fine of element you desire. They measure this in terms of "micron". For example you can get a 10 micron or a 30. The smaller the number the finer the element. I use a 10 micron. When you open the package you get the filer and two rubber O rings. On the top of the filer element there is a metal T handle and you turn (screw) this off. Once removed you then can remove the metal top of the element. Reach down inside the element and pull out the old filter. take note as to how clean of dirty the once white filter material looks. Insert the new filter making sure the attached plastic pull handles are up or on top. Next you remove the old rubber gasket
O ring from the metal top and install the new one, once this is done you replace the top back on filter unit. The T handle has a small O ring and this is also replaced. The T handle is screwed down tight but don't over tighten. Then drain the bowl of all water. You have now changed you filter but in doing so you have entered air into you now sealed fuel system and this air must be removed before you can run the engine
. You have two options. One you use a small hand pump located near your fuel injection pump and this hand pump will pull air/fuel though the system then you bleed off the air by cracking open the air bleeder screw located on the injection pump or....you can fill the fuel filter unit with fresh fuel through the top the same way you put the new filter element inside. No matter, you must totally fill the filter unit and no air must be in the system or you engine
will not run right. In all honestly its rather simple once you have done this a few times. Learn how to bleed air from your fuel system so you are always ready to deal with this in the event you should get air into you fuel system because its only a matter of time before this happens.
