Questions have come up about the replacement time in miles of the fuel filters in fuel injected systems.
The longevity of a fuel filter in these systems is dependent on the cleanliness of the tanks where you purchase fuel.
While it's true that there are recommended intervals for replacing the filter, it's also true that there are variables involved also and should be considered.
Another thing to take into account is this...
The one thing that's overlooked when it comes to fuel filters and fuel injection is fuel flow (quantity).
You can have fuel pressure through something as small as a pin hole (as in a restricted filter) but the flow (volume) isn't there to run an engine at anything more than an idle if that.
Restricted flow can show itself in poor running or even stalling or surging at speeds which can be misdiagnosed as many other things leading to excessive costs in troubleshooting a problem.
