I was kind of confused by that. When I replaced my fuel filter, I pulled the one marked 4 (singularly), tried starting the car , with no response an lost only about 1/4 cup of fuel out of the lines. Caps on the filter ends an Olla ,I was done. But, I kept wondering, "what's up with that other fuse powering the fuel pump too?"
Sorry John this has nothing to do with your OP.
Edit: curiosity got the best of me, so I pulled the doubled marked fuse, car started an ran fine....reminder, its leave season, clean out your cowl cover.
