Fuel Filter?

[freerider8]

Is it necessary or even recommended to add an additional fuel filter after the fuel/water separator filter? I am having my carb rebuilt and want to make sure that I am reducing the amount of sediment and particles that could be in the tank and fuel that can cause me more issues later on. I don't want to put one in if it is just considered over kill or restrict fuel flow more.
Thanks

'n check the Contents of the one ya take off, for anything but clean fresh gasoline,.....

Agreed nothing beyond the standard spin on water separating filters. In fact on the Marine Quadrajet I have the normal filter that is in the inlet housing (for an auto application) is replaced by a low restriction screen. I think the Holley carbs have screens as well in the inlet. A normal 10 micron filter should be more than adequate. If not you may need to clean out your gas tank. If you want the best go with Racor with the metal bowl. They are a pain to take apart though.

Thank you for the responses so far, good to know that this is not needed. I just wanted to be sure so that I am keeping junk out of the carb when it's back and installed. I will definitely be keeping an eye on the filters.

Just to stay on top of it I dump mine out into a Mason jar each season and check it for water/crud. This will tell you if you need to clean out the fuel tank. Ironically even though ethanol fuel (e10) all we have here can be bad, it does seem to keep my tank clean. This is from a 33 year old aluminum tank…

That fuel doesn't look too bad. I dumped fuel out of my boat recently and it looked horrible. Had the color of urine and sediment as well. I am not sure what the inside of the tank looks like since I really can't see into it without taking out the fuel gauge unit. That may be a job for over the winter. Sometimes things like that are better left alone until actually broken. I am hoping that with fresh fuel being used and changing the fuel filters regularly that I will avoid any future issues. Plus I plan on draining the carburetor in the winter and run the fuel down as low as possible before storage.

I think one of the best things you can do with an older boat is clean out the gas tank when it needs it done. There are places that will do this for you, if you don't feel comfortable doing it yourself. It helps avoid chronic fuel system problems.

I will have to look into that.
