It's the last place for me to look for my fuel problem. Checked everything else. Very weak flow to filter. Tried to disconnect valve elbow from top of tank. Can't get it out. It just spins. I've read where guys have cut check ports into the top of tank for cleaning, etc. But I know my problem is with that damn screen at the end of the pickup. How do I get at it? Emptied the tank today (fuel was very clean) and will pull it tomorrow, but then what? Any experience with this? Appreciate any help or ideas. Thanx.
