Today, I was planning to repair or replace the fuel sending unit on my 300D. A post I found on another site said to remove the back seat.

So I did, guess what, not there. However, a little poking around and I found it. All you need to do is remove the first aid kit storage box and there it is!

You need a VERY LARGE socket, 44MM? or, remove the wall inside the trunk, behind the seats(easy,4 screws)and use a pair of channel locks.

Mine turned out needing to replaced. Reading this forum gives me the confidence to really try DIY stuff.

Thanks!
