Sediment Bulb Type Fuel Filter?

I'm getting prepared to give the Stromberg OF that didn't get on with my '23 Runabout another try on the '14 Touring with a circa '19 motor. Stan Howe provided a manual with the carb and early on he recommends a sediment bulb fuel filter. This is a step that I do not care to skip as this car is an older restoration with an uncertain history. The tank may well have contaminants including rust just waiting to cause trouble.
If you have a successful installation, what have you used for a filter & where did you mount it?

The original sediment bulb has a very fine screen filter inside. That screen should be in good condition or should be replaced with a new one. Any more filters in the system will interfere with gravity fuel flow. This could cause problems when going uphill or on hard pull. The original sediment bulb should filter out the dirt in the fuel just fine and should be drained from time to time to get out any water or other particles inside it. I personally have had no problems with using the original or replacement sediment bulb. The earlier tanks are all available new replicas of the original tank. The only tank I am aware of which is not available new is the cowl tank for 26=27. If the tank is merely dirty but not rusted through, it can be cleaned by a good radiator shop.

Thanks Norman, I'm not aware of any issue with the tank on this '14. It may well be fine. I just want to give this OF conversion the best chance to work out that I can. I already met with trouble the first time and that was with a new tank, new bulb under the tank & a new fuel line. I'm not sure where I came a cropper with the '23.
More to your point, an additional filter could cause problems with fuel flow. I sure don't need that either!

An additional not restrictive sediment bowl shouldn't impact fuel flow. Something like this in line should do the trick.

I believe the glass bowl filter from TSC is superfluous. It won't hurt anything, but it's just a repeat of the stock sediment bowl under the tank. Neither the glass bowl nor the sediment bulb will stop very fine rust particles that can clog your carb. VOE. The only cure for that is a clean tank. You're lucky that your tank is good, because the man who was making the tanks Norm mentioned has died, and I doubt that any of the parts dealers still have them in stock. Not long ago Donnie Brown told the story of the current tank situation in more detail. If I were a better researcher I could post a link to it.

My gas tank is in unknown condition. I filled it with fuel and have driven the car something like 100 miles without trouble that I know off.
Dave at Chaffin was recently telling me the story of so many of our parts that are currently unavailable. Even simple things like the clamp on mirror for the center of the windshield are out of stock with no indication when they will be available. I've tried every vendor I know off with similar results, nobody has them. This morning he told me that the spark plug wire set is gone, at least for the time being.
I'm still inclined to put a sediment style filter in someplace. Stan knows his onions. If I have fuel feed issues I'll reconsider the issue.
