loss of power, stalling, no start and a code for lean fuel trim
The fuel filter needs to have a good flow. When the fuel filter gets clogged the fuel stream slows or stops. The vehicle will either run sluggish or stop running.
Your fuel filter is important for maintaining free flowing gas to your engine. If the line or filter gets clogged, your car may sputter or stop while driving.
The engine will starve for fuel and may not run at all.
If any of it gets through the pick-up filter (aka the sock) then gets through the fuel pump (assuming the vehicle is fuel injected) it will get caught in the fuel filter before it reaches the fuel injectors. If enough of it gets into the fuel filter it will clog up the filter and restrict the fuel flow.
it will run lean, eventually causing detonation (pinging) which is very distructive to your engine.
Most times with fuel injection it is in the tank and gets changed with the fuel pump.
Your fishtank gets dirty quicker.
Pretty much the entire fuel system. It gets clogged, the engine gets starved of fuel, and it either doesn't run or else it runs very poorly.
It blows up!!!
If the air filter is not changed in time it gets partially clogged, resulting in poor engine performance; particularly in EFI eingines. Disturbed and irratic idling is resulted along with higher fuel consumption.
Your fuel filter could be clogged up or you could need a new fuel pump.
plugs at around 100,000 miles. blow out or replace the air filter. replace the fuel filter.
