Trailer lights blown fuse
 

2017 f350 super duty. Blew the 25 amp fuse for glow plugs while searching for blown trailer fuse. It sits next to the trailer fuse and very hard to see or reach. Anyway, I can't find a replacement. I've looked at Napa, OReileys and even the Ford parts web sight with no luck. It's number 41 in the distribution box. Anyone??

Looks like you need an "MCASE" 25A fuse.
Check with your local NAPA store: https://www.napaonline.com/en/p/BK_7825544

THank you so much.

Yeah, that style of fuse is a new one to me. Have never seen one before.
