If your still running a mechanical fuel pump you can install a small filter in the glass bowl,
Napa 3039? I think. Add a small spring to keep it in place. And it does not look out of place on a stock flathead.
I'd post you a picture, but I still haven't figured out how to add a pic from my phone.
PM me and I can email it to you.
Sorry, just read the part about no mech pump. ;(
