I want to change my fuel filters but can't figure out where the shut off valve is and can't find it in the owners manual. The manual just says there is one. But not where.
Where is the fuel shut off valve on my 1984 Newport Mark iii?? (Universal M25 xp engine)

Joe is right about it likely being on top of your tank. On my C30, you prime it by holding the key in the start position without pressing the start button
I did look there, although I didnt crawl over the tank to check the aft end. Is that where it is? Or is it on the side (near where our Raycor is and where there is a cutout)?
You really need to trace the fuel line…start at the Racor and trace the line back to the tank. The fuel shutoff should be somewhere between those 2 points.
My guess would be close to where the fuel line leaves the tank.

There is no way to trace it beyond a certain point when it enters the cut out by the raycor. I could tie a flashlight and gopro to a rat to explore, or maybe an endoscopy camera 
. But they sure didnt put it somewhere someone could actually access it.

It should be in an accessible spot…. Not right after (or on) the tank? I would have guessed it would be between the tank and the Racor.There is no way to trace it beyond a certain point when it enters the cut out by the raycor.

What is on the “other side “ of whatever it disappears into? Can you get to that side?
