add on Fuel filter

A friend of mine was looking at my boat and noticed i had a fuel filter that has the cardboard filter inside and told me his mechanic told him not to use the cardboard ones.
Is this info right?if not cardboard then what,plastic?And what is the reason for not using?
Don't know if it matters where it's at but i have it between the bulb and motor.

the more filters the merrier. Buy a Racor. I run a 30 micro, a 20 and then a 10. Yup I'm anal.

I think some paper filters can be eaten up by the oil in the gas. I have used the G2 fram type online filters with diesel and never had any issues. If you go with an in line filter get the steel housing type as you don't want to step on a plastic one and break it.
I have a Fram G2 filter on mine right now, but not enough time on the motor to know if I'll have problems or not.

In my opinion, with a built in tank you should install a water separating filter between the tank and the bulb. Get rid of the little inline filter and replace it with a large canister filter appropriate for the size of your engine.

I have never, or would never use a built in tank without it. I currently use one with the plastic chamber and drain valve at the bottom and really like that best. In the past I've had the kind with just the canister (that looks much like an oil filter), and it was appropriate for that application (inboard), but for an outboard, I prefer the drain-able kind.

If you already have a good water separating filter, you don't need another.
