Fuel filters and why did it let me down.
Why did this filter not catch particles from getting into my carb, the particles are big enough to plug accelerator pump jets and cause my floats to act crazy. So is everyone using this same filter with success?

I would make sure the rubber seal on the filter element is in good shape without any gaps or imperfections, and also make sure the filter element isn't made in China.

Re: Fuel filters and why did it let me down.
These filters should be able to catch particulates up to so many microns in size. you can find out by getting filter specs from mfrs website.
Don't put gas in your tank right after it rains. water does get into these underground tanks (and a little bit of dirt too). If theres rust flakes in your gas tank, you can drain the tank and pull the fuel sending unit off, then run a telescoping magnet down inside the tank to pick up as much of the small rust particles as you can. |

Re: Fuel filters and why did it let me down.
You didn't say what those particles looked like. I notice a rubber hose, (looks like after the filter,) a flexible hose is necessary to counter vibration and engine movement but remember if your using gasoline/eythynol mix, the eythynol will attach and break down rubber as well as some other fuel system materials, even from inside your carbeurator. Then you will find that stuff in your carb. I read a while back that it will corrode aluminum too.
I use whenever I can, straight eythynol free gasoline, 91 octane, it is available in my state, and at small airports. It last much longer and doesn't absorb nearly as much moisture. |

Re: Fuel filters and why did it let me down.
Could it be the filter is not installed properly. It looks like it's on a angle. Yes the hose may be disintegrating also . JMO

Re: Fuel filters and why did it let me down.
It was a factory part on many 50's and maybe early 60's cars, mostly Fords & Chevy's. The classic car restoration places sell them and they're on ebay a lot.
the 'dome top' ones usually go for a bit more cuz they were oem on '55/'57 T-Birds. http://www.ebay.com/itm/GENUINE-AC-G...xY28XH&vxp=mtr . Last edited by dmsfrr; 04-03-2017 at 10:00 PM. |

Re: Fuel filters and why did it let me down.
right, no spring, I have seen similar filters with a spring that assists seating the filter to the top of the bowl. This is imperative that there is a good seal at the top. unfortunately I believe the seal was not sufficient letting the stuff shown below reach the carb. I am going to find a spring.
This is the residue from the vent tube filter that disintegrated long ago. dissolving into very fine particles. I included a photo of the broken filter tube with no mesh left, half of the plastic tube was floating around on the button of the tank.

Re: Fuel filters and why did it let me down.
Make sure the filter housing cap matches the top of the filter element. There are a couple different styles of housing cap that look similar but are Not the same.
The filter element is a friction fit onto the short lip at center. Older filter elements may lose their fit. I'm thinking of looking for a spring too, just in case. The flat rubber ring around the outer edge of the housing cap in the 1st photo is the seal for the glass bowl. . Last edited by dmsfrr; 04-04-2017 at 11:31 AM. |

Re: Fuel filters and why did it let me down.
There just does not seem to be enough sealing the paper to the center tube as well, even with a spring pressing up I have to believe the paper soaked with fuel will give way and still leak a bit. The filter removes as little as 10 microns but the seal is the weak point. Maybe if a smear of soothing like rtv to give a rubbery coat could help it seal.

Re: Fuel filters and why did it let me down.
I don't suggest any sealer as it could too easily clog something up.
To refresh my faded memory I just went out and double checked the two glass fuel filters I have, neither are installed. One is the oem dome top style and the other is a replacement style. I have one lightly used filter and a new Wix brand filter in the box w/ a new rubber seal. I tried both filters in both housings and got the same result. Now I'm more confused. The fuel comes into the housing thru the center hole and straight down into the bottom of the glass bowl. From there fuel goes up to the outside of the paper filter, thru it and out thru the ring of several small holes around the center hole and then out of the housing. However... neither the fiber top of the filter or the rubber O-ring is quite large enough to seal the top outer edge of the filter against the underside of the housing. It's close but not quite. This allows the filtered and unfiltered fuel to mix before exiting the top of the housing. Something is wrong here and I don't have a clue. . Last edited by dmsfrr; 04-05-2017 at 11:18 PM. |

The options I've found throughout my forum searches. 1: housing, gasket, filter, bowl 2: housing, filter, gasket, bowl 3: housing, gasket, filter, spring, bowl #1 did not work for me #2 might work, at least the gasket would hold a loose filter to the housing, unfortunately my filters top paper is not centered on the filter so the rubber gasket will hold one side but not the other, this might cause the side without paper overhang to lift that side causing a bad seal. #3 a spring totally makes sense to press the filter to the housing. At least it would press to the housing evenly, and as the paper wears the spring will continually adjust towards the housing.

Re: Fuel filters and why did it let me down.
Ok, went back into the garage since my eyes are more open. (not 11:30pm)
And remembered to take pictures this time. My 2¢ worth... Option 2 is how it works, but carefully. I'd seen this posted about before and it wasn't clear til I had to try it for myself. The filter goes on first. Then the flat rubber seal over the filter and then the glass bowl. The rubber seal for the glass bowl holds the filter 'up' in place. However, if the rubber seal isn't relatively new and carefully centered over the edge of the filter unwanted stuff can get thru. (photo 3) I wish the rubber seal fit better, or the fiber filter top was a bit bigger. Maybe a different brand of filter and rubber ring fits better??? *Option 1* If the rubber ring were put on first there's really nothing to keep the filter up in place or more importantly, close off the top outer edge of the filter element, letting unfiltered fuel go past it into the outlet portion of the housing. *Option 3* A spring would not hold the filter up any higher than it already goes. (photo 1) When the filter element is fuel soaked a spring might cause it to try and collapse. ??? Quote:
With the center hole of the fiber top tight on it's lip in the center of the housing cover, and outer edge of the filter top fully covered by the rubber seal, the filtered and unfiltered fuel should be separated. . Last edited by dmsfrr; 04-04-2017 at 11:15 PM. |

Re: Fuel filters and why did it let me down.
Hey dmsfrr, well that sure made it clear. Thanks for the info and the time it took to post those instructions. I just could not believe #2 is the way it works, just seems like it had to be missing something. Ok, #2 it is.

No one has told me I'm full of it, yet. Maybe I got it right. . Last edited by dmsfrr; 04-05-2017 at 10:24 AM. |

Re: Fuel filters and why did it let me down.
FYI.
I looked in the big red '55/'57 T-Bird Restoration Manual put out by CTCI hoping to find some guidance but if it's in there I missed it. |

Re: Fuel filters and why did it let me down.
I received the new filter today, it made perfect sense once I Slipping the gasket over the filter and installed them according to #2. So much better than my first attempt. I can see how the seal is way better than before. I hope everyone with a filter like this sees this post and installs correctly.
By the way, I cracked open my carb and there was so much garbage throughout my new carb that it was no wonder I was chasing problems. So excited to test drive her tomorrow. Clean tank, new fuel line that's not pinched closed, filters in place, cleaned carb, oil changed, valves adjusted, decarbonized. 2nd filter for the first tank of gas. I am ready to roll.
