Gas Filter

Recommended Posts

There is a quick way to check the main gas filter and it only takes a second to do. Place your thumb on the input and your little finger on the output.  If the input is hot and the output is cold, then the filter needs to be replaced. 


Buy the disconnect tool.  Don't be cheap.  Most cars use a circular tension retainer and it is so easy to break.


Other cars have the filter at the engine compartment and the fuel line bolts on to the filter.


There is also a little bitty filter at the neck of each injector that is fairly easy to replace.


Lastly or firstly....there is the gas tank.  It should be cleaned every couple of years, not only because of contaminants like water and such, but the sock filter at the bottom of the pump assembly gets hard and crusty (beyond normal DIY talent to replace).
