Product Recommendation for Cleaning Tank Strainer

[shertex]

I have reason to believe that I may have a fuel restriction at the tank strainer on my 91 300D (both fuel filters have been replaced). As that part of the fuel system has, to the best of knowledge, never been touched, it seems like it would make sense to replace the strainer just on principle...have one on order.

But, before doing that, would it make sense to try an additive to dissolve whatever is clogging the strainer? If so, what product might be well-suited? I'm looking at the various Star Brite products...not sure which if any would be a good choice.

Thanks for any help.
