Fuel Filter

Post by captain marty »

I’ve tried installing an inline fuel filter on the tube coming from the sediment bowl a couple of times with poor results. Seems the gas doesn’t run through the filter quick enough and the truck runs rough. The filter is about 1.5 diameter X 1.5 length. Anybody ever used a filter like this with better results than I’ve had, or is there something else I should look at. If so what type or brand.

Thanks,
Marty

I see that filter is for the glass sediment bowl/filter, not the original cast iron sediment bowl/filter. I've always gotten by with the 2 filters Ford supplied: the cast iron one on the firewall and the one in the carb . Why do you need a third filter? When I had dirty gas tank problems I got the little screen that goes on the tank outlet.

Hi, I have tried the inline paper filters, as well as several members in my local Model A chapter. Sometimes they will work, for a while, and then have a reduced flow. Gravity feed does not work with those inline filters,I think that the paper gets saturated and swells. If your sediment bulb is put together properly then you should not have a problem. You could put on a late 31 sidebowl carb and its unique sediment bulb, that bulb will also work with a B carb, then you would have the firewall filter as well as the carb filter, if you want overkill on filters.

The finer-filtering filters will not work on gravity-fed fuel systems as they restrict the flow too much. I have run into this problem a couple times in the past with garden tractors. I've used filters rated at 150 microns or more in the past, and they seem to work fine.
