There are four filters between you and the gas in the underground tank.
1) Dispenser filter (that's the "pump")
2) Sock filter on the pickup in your gas tank
3) In-line filter in your fuel line (that's the one you replace)
4) Micro-filter in the injector itself.

The probability of grit getting to your injectors is virtually zero.

The contamination you are vulnerable to is WATER. Gas station tanks
eventually acquire a certain amount of water as a matter of course, just
because of their crime of existing on the planet Earth, where there is free
water. When the underground tank is refilled by that big truck you see
occasionally, that water is stirred up and temporarily gets suspended in
the gas, and gets pumped into your tank. That water passes through EVERY
filter in the system, even the very best ones you can buy.

The station is /supposed/ to take a newly-refilled tank off-line for a
couple of hours to let the water settle out, but few actually do that,
which is why you're supposed to lessen your chances of taking on water by
never filling up at a station that's being refilled. I actually go up to
the driver and ask him what tank he's filling. If it's not my octane, I gas
up.

Having said all that, most people are not at risk so much from water in the
gas from the gas station, but water they introduce into their system
THEMSELVES. In other words, most corrosion-based fuel system failures are
due to SUICIDE. Many people drive around with part-full or mostly empty
tanks. They will do this regularly, then allow the level to get very low
before they go and put five bucks in, just enough to get the Low Fuel light
to shut up.

That last paragraph means that they are allowing condensation from the bare
tank walls to run down into the gas every night. Over time, that water
builds up considerably, causing rust and scale inside the tank. Eventually
that water gets sucked up by the fuel pump, causing corrosion in the pump,
lines, injectors, pressure regulator, all sorts of components.

Then they wonder why they have fuel problems. Then they blame Honda, or the
gas station.
