100 micron filter at tank outlet enough?

Filter manufacturers say use only 100 micron filter on suction side for carbs. I have a new one ready to install by the tank outlet. OK to eliminate the one by the mechanical F.P.? I've also got a new high-flow 40 micron that was going there, but might not need it (and I wouldn't be following the instructions).

Concerned about particles in the 40 year old hardline. I did run some braided wire attached to a drill through it couple years ago, and last week put some Gumout fuel injector cleaner in the tank, hope it got most of whatever was left in the hardline.

The electric fuel pump by the tank is removed.

If your hardlines are in question I would keep the 100 micron filter up by the carbs and a 40 micron by the tank.

I have also done the braided wire with a drill on on old fuel lines. Even though only gasoline has run through those lines it is surprising how much muck comes out after a mechanical cleaning.

yeah, I had to work it for a half hour to get the wire all the way through.

I want to pour some Gumout in full strength from the engine bay and let it sit for a while. Scared it will hurt the hoses at the tank though.
