$2.95 part is worth every penny.

Yesterday was "clean the trunk" day for me. When I pulled the back panel off to clean behind it and check out the gas tank, bingo! The factory fuel filter sitting there with a big black gob of goo resting on the bottom. I had already bought a fuel filter for $2.95 so I had it in my box of goodies. It took all of 10 minutes to replace and afterwards, I actually had to take the idle down about 250 RPMs. I'm beginning to think there might be something to this changing your fuel filter occasionally.

Some people suggest having 2 filters, one just before the fuel pump. Is that really necessary?

I don't see a need for two. One in a location before the pump that is easily accessible is all I see as necessary. If there is a lot of debris in the system causing a person to feel the need for two, then the system should be cleaned.
If debris wears a hole in the filter element, the filter was long overdue for replacing.

I think it depends upon the individual car
how many fuel filters are required as well as
where you live. Windy, sandy places require more
filtering effort that inland, soil places.

My '69 TR6 has 100% all new fuel lines, new carbs,
new fuel pump and a refurbished, clean as whistle
fuel tank.

In order to keep the carbs from flooding the engine bay
it required a filter just below the fuel tank, a filter
just in front of the fuel pump, a filter just after the
fuel pump, a filter at the front carb and a filter at
the rear carb. A total of five fuel filters.

Sounds like overkill but the carbs no longer flood gas
onto the hot exhaust manifold due to sand and fine grit.

I work with engineers all day, so the old joke about a camel being a horse designed by engineers is true, but this is what happens when you have an architect involved.

Dale, I don't think that the new Boeing Airliner has that many redundant filters for it's engines.

Just kidding, Bud. You are running now, flood free, so I'll be quiet.

Likely depends a bit on the individual, too. My TR3A seems perfectly happy with no fuel filter at all beyond the original sediment bowl, which does catch a fair amount of crap, crud & corruption.
