What are the first symptoms of a clogged or dirty fuel filter?

I have begun to notice a few occasions of:

Stumbling idle after a WOT run

and,

high RPM cutout.

Just recently. I have 18,000 mi on the current stock filter.

What are the usual symptoms of a clogged filter?

Thanks.

I have changed my fuel filter about every 10,000 miles and always notice crisper throttle response afterwards. The first time I changed it was at 42,000 and that was because of it running rough and stumbling.

Change it. It's way over due. Stumbling, rough idle, minor surging, lean condition or detonation when running hard, racing or WOT. I wouldn't go more than 6-10K. Especially if there are performance mods. on.

While living in Key West, my new 1964 Corvair Spyder(factory turbocharged

) just shut down. I don't remember the mileage on it at the time but the filter was the culprit. Upon inspection, it was stuffed with among other 'gook', some small Florida crawfish(they are not lobsters, btw.), shrimp, and Key deer scat

.
