Gas Fuel Filters

Any recommendations for a marine rated gasoline fuel filter? This will be the post-pump filter for my 250 Hp Chevy 327.

I will have a water separator before the pump, 60Gph, 10Micron. It says it can only be installed before the pump on the suction side as it is only rated for 1.5PSI working pressure.

I am not looking for this kind, one started my friends Cougar on fire.

I have this one in my Falcon, no issues, but its not marine rated and it does not have a bracket for mounting

Some relevant requirements from the USCG:
  • 183.536 Seals and gaskets in fuel filters and strainers. (b) Each gasket and each sealed joint in a fuel filter and strainer must not leak when subjected for 24 hours to a gasoline that has at least 50 percent aromatic content at the test pressure marked on the fuel tank label.
  • 183.556 Plugs and fittings.
    (b) A plug used to service the fuel filter or strainer must have a tapered pipethread or be a screw type fitted with a locking device other than a split lock washer.
  • 183.570 Fuel filters and strainers: Installation.
    Each fuel filter and strainer must be supported on the engine or boat structure independent from its fuel line connections, unless the fuel filter or strainer is inside a fuel tank.
  • 183.590 Fire test. Each fuel filter, strainer and its connections will not leak more than 5 ounces of fuel in 2-1/2 minutes after the fire test in 183.590.

You're making great progress on your boat !

Here are some inks to marine-rated fuel filters and heads. Look for the High Volume filter heads with 1/2" NPT Inlet/Outlet ports for performance marine engines.

Thanks Paul! So do you have a water separator before the pump and a water separator after the pump? What is throwing me off is that the filter you linked (GLM 24940) says it is a water separating filter (but it does not have a bowl). Would I still use the S3228TUL with the bowl before the pump and the GLM 24940 after the pump (not sure I have a good place to put it though). See pic.

The 025--RAC--10A looks like a marine rated (I assume) inline version of unscrew-able see-thru filter that I am not a fan of. I suppose I could make a bracket for it; this would be better to save some room.

I suppose this thread would be better Here (if a moderator wants to move it that is fine by me).

Also Paul, can you take a look at the last few posts in my thread here and comment on the cable steering setup (spring or no spring).

USCG rule says the filter need a metal bowl if it is enclosed. If the bowl is in an open area it can be clear. :?

Why do you need another filter in addition to the Fuel filter/water separator? My 1991 351 donor motor didn’t have any filtration after the water separator filter.

My diesel only has the one filter. It is mounted on the engine. I put a 10 micron filter on the fuel line for the Yamaha. The Yamaha has a filter inside the cowling also.

Same here I just have a water separator/filter like Paul shows. On the suction side just before the fuel pump.

I thought that I did (per coast guard pic), but maybe not; I am open to suggestions.

Here’s what happens when a fuel filter leaks on top of the engine. It was a rough day.

Yep, same thing happened to my friends Cougar; did you fix it up? I will stick with the one remote mounted filter / water separator.
