For those of us who are mechanically challenged would someone be kind enough to pass along some of the basics about changing fuel filters. On the twin Crusaders I believe I am looking at 3 filters (one a large cannister filter on the main fuel line followed by two smaller ones - one for each carb).

On a previous post I believe someone mentioned that they had to do this several times to correct poor engine performance. If that's the case I had better know how to do it myself.

Is this as straight forward as it looks or are there some do's and don't's to be aware of.

Thanks

Normally there are two fuel filters. One just before the fuel enters the carburetor (about ½ inch wide and 1 inch long) and follow the fuel line and there should be a canister type about the size of an old orange juice can. Sounds like you may have a third which is a water separator coming from the tank. The one by the carburetor will take two wrenches and don’t turn the solid fuel line or you could cause damage. The canister is just spin on. Make should there is no leaks as I had a problem sucking air after changing the filters and the engine would not keep running.

I put inline filters in prior to the regular filters temporarily. That way I could change them fast, easy, and cheaply.

Dale had a great idea, he put a temporary electric fuel pump in and ran all the gas through a filter and right back into the tank to clean it out.

Thanks for the advice.

Bruce you are quite correct about the first filter serving as a water separator. It is about twice the size of the other one and has a bleed-off at the bottom to check for water.
