70 250C Alternative for original fuel filter

So I'm ordering up filters for several cars to get a quantity discount... And while I'm pulling numbers together, I just realized that my 250C does not have a fuel filter - of any kind - primary or secondary.

One of the previous owners removed the mechanical fuel pump and replaced it with an electric pump. There is no primary filter and definitely no secondary filter.

Can anyone recommend what I could use for the secondary filter? I have the little inline primary filters. But now I need a replacement for the secondary. Suggestions? Thanks.

There should be a fuel filter in the gas tank. Check out what mine looked like
after sitting for many, many years.


Also, I just put in $5 fuel filter right after the fuel pump. Is has a clear body so
I can visually inspect the fuel.

I've got a huge one from a Ford - it filters out teeny tiny bits of crud and it cost me all of $9. It's right after the fuel pump.

If you are keeping the electric pump then install the filter AFTER the pump. Running the pump dry due to a clogged filter is the worst thing you can do to an electric pump. The in-tank strainer is sufficient for filtering the fuel before the pump.
