Yeah no I changed the fuel filters recently and the prefilter had some black stuff in the bottom since its been a few years since both filters have been changed. I ran some startron through the tank shortly after and when I was under the car I looked at the strainer bolt and the whole thing looked brand new like it had been changed recently. My father later that night told me he changed the strainer a few years back and runs startron through there every year, also the fuel that came out was perfectly clean so I think the strainer is perfectly clean and I'll go after some other things on the vehicle. I also changed my fixed fan to a fan clutch off from a 300sd recently and that helped performance a little bit too.
