2004 Z06 fuel filter replacement
I had my car on the dyno yesterday (after a cam and longtube install), and found that the car would start losing fuel pressure rapidly... idle was 60 psi, then right at WOT it'd drop down to about 50 psi. not sure how much lower it would have gone, but we didn't check. In any case, the tuner is fairly certain it's a clogged fuel filter.
Being an 04, I understand that the fuel filter, for some stupid reason, is intended to be a non-serviceable type of thing, and is located in the tank?!
Has anyone replaced their filter on 04 cars before, and how involved of a process is it? Any other ideas of what could cause fuel pressure to drop like that? The car is relatively high mileage (a little over 100k), so a dirty filter seems to be a reasonable assumption.
Anyways, thanks for any help!

If your loosing pressure you most likley have a fuel pump issue. How much HP are you making? If it were me and i was going to remove the tanks, I would be installing a high volume pump.
I had 45,000 miles on my 02 Z and i changed the filter. I cut it open and it wasnt that dirty.

More than likely a weak fuel pump with over 100K miles on it..
