Stanadyne FM100 SVO Biodiesel Fuel Filter/Water Separator

Two 30 MICRON FILTERs INCLUDED - LAST ONE!

I set out to find a better filter. After spending hundreds of dollars testing various filters I settled on this Stanadyne FM100 Series unit. It is extremely well engineered, the elements are super easy to change on the road, and it has some great features and upgrades. To heat it you can build your own heating coil or purchase my custom build coil housing. This is one fine filter unit that won't break the bank!

INSTALLATION TIPS:

There are a couple different ways you can install the FM100 water separator filter. It can also be installed in a number of different diesel models from the early 1960’s to the late 1990’s. It is not possible to cover all the details of the exact installation in every model / chassis. You will have to do a little “engineering” on your own to get it installed just where you want it and how you want it to filter you diesel.

 

Here are some general guidelines:

 

Location in the fuel system: 

 

You can install it either BEFORE the engine driven lift pump (located at the bottom of the fuel injection pump or AFTER the lift pump (this is how the factory main fuel filter is located).  If you have a strong healthy engine lift pump you can install it before but remember if will be “sucking fuel” through the FM100. If your lift pump is worn and weak then this may not work so well. You can install a boost electric pump back at the rear of your Mercedes if you desire extra boost pressure (recommending if you are running vegetable oil for fuel). If you install it before your lift pump then you can leave the factory fuel filter in place and you do not need a pre-filter ( The FM100 will act as the prefilter to the injection pump.

 

If you install the FM100 after the lift pump you should remove the factory fuel filter or bypass it. Then will will need the pre filter installed BEFORE the lift pump to protect it. 

 

Making new fuel hoses to reach the FM100:

 

If you do install the FM100 after the lift pump and bypass the factory main filter you can use the fittings on your clear hose to make new hoses. Just cut the plastic hose off the banjo fittings - then install 5/16 rubber fuel hose over the barbed ends and use hose clamps.
