Is it advisable to install an inline fuel filter along the fuel line for my 80's merc 4 cyl ?<br />Also is it advisable to add fuel additive when the boat (and gas) sits for a few months ??<br /><br />As advertised below.<br /><br />"98 Marine Fuel System Cleaner: Cleans the fuel tank and fuel system while an engine is in operation. This cleaner increases fuel economy, removes water from the entire fuel system, helps eliminate rough idling due to gum and varnish build-up, and extends spark plug life by reducing fouling & mis-fire. It is Highly concentrated to blast carbon quickly and effectively."

Re: Fuel Filter

In my humble opinion I would not run an outboard without an inline fuel filter.There are several different types available a water separating one is the best.<br />As far as fuel additives go I have never used one.Some people swear by them so I suppose they might have some value.I find fresh clean fuel a good TWC3 oil & a good filter combined with regular servicing sufficient to keep my motors running well. :cool:

Re: Fuel Filter

Just my opinion. Any additive (solvents) concentrated and aggressive enough to remove existing gum and deposits in the fuel system and engine would adverse affect the way the engine runs and deteriorate the hoses, seals, and gaskets on your engine and carburetors. <br /><br />The corrollary to that is that if it is safe enough to use the concentration will be low enough so that the impact on deposits will be minor at best. If I say that my product helps to remove deposits, but the "help" is a .003 per cent reduction in deposits that is a true statement but of no practical use to anybody.

Re: Fuel Filter

I've always used an in-line fuel filter and have never had any "dirty fuel" problems. The only additive I use is fuel conditioner when the motor is not going to be used for sveral weeks. at a time.

Re: Fuel Filter

If you are not going to grain the tanks at the end of the season, fuel stabilizer IS a must!!!-not doing so is asking for trouble- varnished, gummed carbs.Adding solvents to your system can deteriorate seals , hoses, etc.BUT if used sporadically I don't think there is no real harm.<br />The buzz word- "sporadic"- meaning only if it's absolutely needed- short of a overhaul.<br />The secret is upkeep-clean, fresh, water free <br />gas. Water separators are a must, and an inline <br />fuel filter is always a good idea.
