In need to plug this hole, but can't find any bolt that fits.
Seems to bo 13mm, cause 14mm bolts don't fit and 12mm are to small.
But I can't find any 13mm bolts.

have you tried a 1/2" bolt?
13 millimeters = 0.511811024 inches
.
Remember to find the right pitch size.
If you are in the US, Ace hardware is the go-to for me.
Otherwise order online.

I'm europe, hard to find an 1/2 bolt.
Might be 1/2 UNC? or 1/4 NPT or 1/4 BSP.

For anyone that's interrested.
I found that the correct bolt was an:
British Pipe Thread ( Whitworth Form) -- Parallel (BSPP/BSPF) -- (G)
Size: 1/4
A 1/2 inch UNC wil NOT fit, I haven't tried an 1/2 inch UNF that might also work.

While your in there you can replace that kinked hose.
If that really is a pipe thread bolt??? make sure you use some pipe dope or Teflon tape when you install the new bolt or it will leak.

It's not a pic of my car, my hoses are ok.
Yeah its really is a piper thread bolt, weird stuff.
Hmm haven't used any teflon or dope.
Did used a crush washer between there, and sprayed some carb cleaner to test for leaks.
Seems to do the trick.
