#8 fuse blowing

Does anyone Know what is on the number 8, 30amp fuse under the hood?
It blew the other day and the truck shut down.
I know it runs the IDM and fuel bowl heater, the bowl heater has been unplugged for years.
Replaced the fuse and the truck runs again, just would like to figure it out so it doesn't die on the freeway again.

97 f350 crew cab 4x4 7.3 mostly stock work truck

Thanks, any help would be appreciated.

Re: #8 fuse blowing

All #8 powers is the IDM.

#22 powers the fuel bowl heater and a few other things. Sounds like your IDM may be on its way out. Pull it out and shake it up by your ear and see if you hear water in it.

Well I pulled the IDM, can't hear any water in it.
I may have to try replacing it.
Does anyone know a good source for these?
