On my boat the solenoid pulled in would shut down the fuel supply. It is engaged by completing a circuit with the push button at the helm - or a short across the two connectors.
Closer... Very warm

Relay circuit on the engine at the starter. Original Lukas UK relay on it. Relay was forcing the Solenoid plunger to remain closed. Not allowing fuel to enter the engine.

Trouble shooting the engine like you all did. Before checking the relays.

I learned the first thing to is check the obvious.

Crap! I just read the thread for the first time and that was gonna be my guess!!.... But seriously, a relay at the starter operates the fuel shut off solenoid? Does your fss pull and maintain to run- or pull and maintain about 10 seconds to kill? Cause if it pulls to "run" I would think the starter relay operates the "pull in" coil of your fss (needs more amps), and after starting the "hold in" coil would then get fed by an ignition source. Just wondering.

Good question. I think the relay burned out when I shut the engine down last time because the solenoid was in the retracted position or closed so no fuel was getting into pump.

The lesson I learned was check the electrical before going into the mechanical. If I just assumed it was a fuel delivery problem I would have started chasing pump and air bleed issues and never would have gotten the electric figured out as quickly.

So far as I am concerned there is an especially hot place in Hell reserved for whoever it was decided that the fuel shutoff had to be operated by a solenoid. What in the world was wrong with the old Morse cable? If it ain't broke, then please don't fix it!

My Perkins don't have a relay controlling the power to the fuel shutoff solenoid. The power to the FSS comes through a single wire from the push button stop switch at the helm. No power, the engine runs; apply power to shut it down. Must be pre-Lucas. But I wish I had Morse cables instead.

Does yours require power to open the fuel shutoff? Remove power to shut down?

Reminds me of the Jaguar fuel line to the carburetor.

A possibility of a vapor lock when a hot engine is shut down on an extremely hot day is cured by a coil from the Air Conditioner system integrated into the the fuel line. Brilliant - works well.

But, turns a $2.00 fuel leak into a wait two weeks and $265 dollar part.

I think a pint of Guinness (Brilliant) long wait makes more sense to the passengers.

Mine requires a relay connection from plunger to relay to solenoid.

Ah...Lucas..Prince of Darkness!!
I raced British sports cars in SCCA for 12 years and the first thing we did was replace all Lucas parts with non-Lucas parts!

The three positions of a Lucas headlamp switch: off, dim and flicker.
