EDE 1406 Fuel Filtering? How much is enough?
Have inline barbed filter between tank and S.W. fuel pump.
Stewart Warner pump has intergal filter. Is it essential to have another filter at point of entry to carburetor,or is this a case redundancy? Desire to have all hard pipe over engine, from flex connection at pump.. Realize this may be an academic query, but no pro here. Thanks of course for any input.

Walt, just to put things in perspective, the source of fuel contamination is at the filler, once it's in your tank you've got a "sealed" system except for airborne moisture ingress through the vent.

That said, with the exception of condensation indicated above, and any deterioration of fuel system components, the "trash" comes with the fuel. Filtering at the tank end of the system, or anywhere upstream is acceptable. I typically mount a spin on type filter near the tank (Ford OE item, Fram also makes a similar unit that has a cartridge in a can). One hint, if you see a tanker truck dropping fuel at your station of choice DON"T STOP. Come back later. The dropping of fuel from the transport will stir up all the tank "bottoms", which contain particles, rust, and water. A half hour later most of that stuff will settle out.

BTW, like the Unis..............is that a '50's track car, or modeled after one?

Hi Bob. My vintage roadster is of the Miller/ Allard design-in 1930s.
Started out in '57 to make a vintage body of the type used at Indy during this era. Had a 6 cyl. Studebaker engine originally which I swapped for '66 327 Corvette/stock with 4300 original miles. I do thank you for all the input. Direction on fuel tank unloading sure makes a ton of sense. The screw on tank filter is for sure a must as I read this. Have a great day. Enjoy your postings tremendously.
PS Unis / Short for vanity license plate which is "Unique"
