Wally - now to contradict an earlier post.

I have an inline filter between the shut off valve at the bottom of the tank and the steel line going to the pump.

I also have an inline at the entrance to the carb.

The bottom one required changing about 3 times before the tank grit was sloshed out from driving.

That is the only time I experienced fuel starvation. I didn't know what the junk would do to the pump and figured I would rather not pump it through.
