MochetVelo Posted October 11, 2018 Share Posted October 11, 2018 Can an in-line fuel filter be used in gravity-feed fuel lines? I've read they don't pass enough fuel. Phil Link to comment Share on other sites More sharing options...
PFitz Posted October 11, 2018 Share Posted October 11, 2018 I've installed them in customer's cars just before the carb, and before the vacuum tank once the tank has been properly rebuilt. And I've seen many that others have installed. Those cars ran fine. Think about how small the openings are in float needle seat and carburetor jets. The filter only has to pass a little more fuel than those jets do. As long as the filter is not overly contaminated, there's no problem flowing more than enough fuel.

Spinneyhill Posted October 11, 2018 Share Posted October 11, 2018 You might consider a clear case so you can see how much dirt is in there? You never know with the metal case. 1 Link to comment Share on other sites More sharing options...

JV Puleo Posted October 15, 2018 Share Posted October 15, 2018 I never had a problem with them on my 1910 REO with the gas tank under the seat. I also used the clear ones until I made a new tank. Link to comment Share on other sites More sharing options...
STUDE48 Posted October 17, 2018 Share Posted October 17, 2018 I just installed a glass sediment bowl with a fuel shutoff that was sourced from the local tractor supply. And plumbed it into the vacuum tank and the carb Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted October 21, 2018 Share Posted October 21, 2018 (edited) On my 1925 Buick, there is a screen on the gas tank pick up tube. There is also a small thimble sized screen on the inlet to the vacuum tank, and the same small screen on the carburetor inlet. In 1926, the big advance was filters on the air, oil, and gasoline. They added a fuel filter on the outlet to the vacuum tank. The key is a filter with sufficient pleats to prevent pressure drop while filtering the volume of fuel needed. I prefer a filter to a sediment bowl, and this does both. I purchased an AC filter from www.restorationstuff.com They carry the AC replacement filter elements as well. Photos are of the gas tank screen, a 1926 gas filter on the vacuum tank, and the new filter for my car. I thought about installing an inline filter in the fuel line from the gas tank to vacuum tank, but that feed is dependent on the amount of engine vacuum available to pull the fuel so I am not as comfortable with a filter there.
