Fuel Filter

Is it possible to put two fuel filters in series on one line? I want to do this because I am afraid there is a lot of debris in my gas tank and I figured it might allow me to change out the first filter out on the water?

Yes, it's very common DSK

Doug, if the first filter is responsible for both large and small jps

Nope. If the amount of gunk in the fuel is the same, then DSK

Better to put them in parallel with shut off valves on each side. Run one at a time. When the first one is clogged, close the shut off valves for it and open the valves for the other one.

Common arrangement on many diesel powered boats.

I have 3 in mine, a big spin on water separator filter, one of those glass ones you can see fuel flowing in and the stock filter in the engine. no problem.

A good idea and it'd be best to start with a coarser filter and put a finer filter in the second unit. They'll do a better job by exposing more filter surface to trap different sized particles and thereby help ensure the first filter doesn't get clogged by smaller particles.
