What components run off EFI Fuse?

Update,
Raised the car up on all four jacks, let it run for about 15 minutes so it was nice a hot. Bumped around the exhaust and o2 sensors and couldn't replicate the problem.
Next thing I tried was removing the EFI Relay in the engine bay fuse box as recommended by this thread here;

Car wouldn't start at all and fuse did NOT blow. Put the relay back in and the car started up just fine.

I had the same issue, EFI 2 7.5 amp fuse when I go up hill it blows and my MAF doesn't work and it goes into limp mode and car stalled
I thought it was my O2 sensor downstream, possibly a wire shorting due to spacer install in tight spot.
I removed spacer and put silicone around wire entry on O2 sensor and so far no more stalls or fuse blowing.
I have not fully tested this but just went to spots the fuse blew before trying to replicate and it didnt.
