Fuse 4 is definitely on the load side of fuse 6. But fuse 4 should be an 8A and I think fuse 6 a 16A, so a funky oxygen sensor heater shorting out would be expected to take out 4 before 6.

Is the fuse blowing? That means, does it part in the middle with burn marks around the open section? Or is it melting because of overheated contacts. If the latter, try cleaning the fuse holder and tightening the spade connectors on the wiring to it.

I don't know of any common causes of that fuse blowing, but have heard someone report frayed wiring at the main fuel pump terminals. Also, I can't imagine a fault in the relay that would blow the fuse.

Here's a link to a wiring diagram showing how 4 and 6 get wired:
