Proper Fuel Filter for an Atomic 4
Looking for a proper gas fuel filter for my A4. I see many filters that are for diesel and believe its a very common mistake to think you can use these with gas. Most are for outboards and not for down below in an enclosed space. USCG also does not like non-flame retardant bowls for inside use. Have to agree with them there. Any thoughts on finding a set up with a metal or glass bowl ?
Thanks All. |

Hello magi.
Here is the filter/separator offered in the MMI catalog, which has a metal bowl: https://moyermarine.com/product/raco...fpmp_05-1_349/ Jack. |

magi..welcome, and right on the above posts. You want the Racor 320R with the metal bowl linked above. I will comment from personal experience that it is important to lubricate the rubber gaskets for ease in later servicing.

Let me add that you should check your filters with a magnet. If a magnet sticks, they're going to rust. And the rust particles are going to go downstream toward your carb. I spent a Summer tracking down carb issues. Turned out to be due to my secondary filter (the one of last recourse) rusting and sending rusticles to the carb.

Then there's the USCG metallic construction requirement for inboard gasoline installations or said another way, no glass, plastic or see-through materials of any kind for filter or sediment bowl construction on a gas inboard.

I too use the sierra filter. They're inexpensive enough that I just replace it every spring. Never had any rust.

I agree with Ed. I got rid of the bottom-draining racor. I also use a sierra spin-on filter- just pull the whole filter and throw it away. Besides just having 1 o-ring to seal, I always worried about the drain at the bottom of the racor leaking. Yes, the drain does allow you to check for/drain water, but at 10 bucks or so per filter, I prefer to just change filters.

Further, my policy is filter cartridges are consumables and that includes a polishing filter (which I choose not to have).
BTW, I run on a steady diet of ethanol laced fuel (California), no problem.

Ethanol gas is all we have here too. It is fine until water gets in it, filters won't fix that. A new fuel fill cap O-ring does though

. . . and from what I'm reading in this thread you're not alone to some degree. I'm sorry but I don't get it. What am I missing? Why change one filter annually and not the other? Especially when it can produce exactly the contamination it's supposed to be protecting you from?

I am halfway tempted to just replace the hose barb on the carb with some better kind of fitting and do without it. |

Yep, one of my projects is adding them to my electric fuel pump and my spare for easy change-out.

All that stuff came off the next day! Now with these fittings I will have the correct marine hose that already is fire-resistant I do so hate having to cut the hoses every time I take something apart, yanking them off the barbs rips them up. |

K.I.S.S.
One of my practices on ANY fuel line assembly with barb fittings is to spend some time, sanding, filing or rounding the edges on a lathe to eliminate the sharp edge of the barb but leaving the bump in a rounded smooth sealing surface that still keeps the hose from slipping. This also keeps the "NEW" hoses from being cut by the sharp barb when clamping.
This really reduces any cut fragments getting into the stream when doing an emergency R&R. I have used many true "AN" fittings on cars, hot rods and buggies but I will not consider them for a boat in salt water. Also I don't like the braid hiding the condition of the hose or hiding a leak. I did many port on port Webber installations with the AN fittings as well as the cooling system for no other reason than "LOOKS". Dave Neptune |
