About to crack 100K miles and never been touched. Was thinking about replacing it. Still running like a top after 15+ yrs.

Well every other filter I can think of requires replacement at some point.

Doubt this would be different.

I bet you stop thinking about it when you realize it's likely in the fuel tank attached to the fuel pump.

On a gas burner, use Chevron w/ Techron, good stuff. I haven't changed a fuel filter in forever.

Diesel truck gets a new filter(s) every other oil change.

if it aint broke, don't fix it. leave well enough alone. I've only changed one, and that one was easy and needed it. Most are very difficult now but last a lot more than 100K miles. If yours is over 15 years, it might not be in the tank, though.

Mine is outside the tank. 20 minute job once the car is lifted.

Gas itself is "clean."

The underground gas station storage tanks with dirt at the bottom are the problem.

Never get gas when you see a tanker truck filling them, as that dirt is being stirred up.

Gas pumps have 10-30 micron filter to catch sediment from the underground tank

good luck with getting it pulled off..and have plenty of towels available. Replacing the one on my old Ford Explorer Shittrac was a damn pain in the knuckles!

In a perfect world, gas pumps are well-maintained, but anyone who drives can tell you that's not always the case. Leaking fuel, water in the gas, etc.

State agencies charged with inspecting these pumps (in Texas, it's the state department of agriculture) are overwhelmed, understaffed and underfunded.

Many of the fuel filters are self cleaning and inside the gas tank with no replacement required. Best advice I’ve received was never full up when the tanks are being filled at the gas station. The gas trucks kick up all the shite that settles on the bottom of the tanks.

Also Techron is the best additive for direct injection engines to combat carbon buildup.

Faulty gas pumps mean you could be buying watered down gas, gas with sediment in it, or getting less gas than you pay for.

A recent report by CheapCarInsurance.net found that gas stations across the country are failing inspections. The study looked primarily at violations that occurred in 2016 in North Carolina, Florida, and Georgia.

Water leaking into gas accounted for the most violations in Georgia, at 20.7 percent, while more than 1 in 10 violations involved faulty discharge, and nearly one-third of all pump leaks occurred with regular-grade gasoline.

In Florida, nearly one-third of pumps pumped too slowly, and more than 1 in 10 stations failed inspections.

In North Carolina, nearly 24 percent of all gas station violations involved the discovery of sediment in the fuel, and more than 20 percent of the state’s gas station violations related to water contaminating the fuel.

The fact that these three states are the only ones highlighted in the report does not mean that gas station violations are exclusive to them, nor does it indicate these states have the highest amount of violations; in fact, these states were selected because they had the best data available on the matter.
