OM617 questions

Did a little bit of work on my 1980 W116 300SD this weekend.
Deleted EGR and temporarily ran alternative intake until I decide if I want to buy another T-bracket.

When I replaced fuel filters, I ended up with a leak at filter housing. Even with new washer.
I want to update to the later filter housing anyway, so now is a good time.
Does anyone have a good one they would like to sell?

Bought a new cigar hose, turned out to be too short. I guess there's a long and short version. Ran regular fuel hose temporarily.

Also noticed I have oil leaking up through a valve cover stud. I replaced the gasket when I did valve adjustment a couple weeks ago. Is there supposed to be any type of seal or washer under those nuts?

I'm missing a hood latch striker/buffer. If anyone has a good one laying around I'll take it.
