Technical Gravity feed fuel tank

Go to a small engine shop that services riding mowers. Some of those operate on a valve that opens when it's powered and shuts off with the switch

 

My forklift (propane) has a solenoid valve. Opens when the keys on (NC valve). The forklift was a “warehouse” forklift. 6k Yale, narrow and compact. Anyway, these things ran all shifts with the valve energized. I bought it used, after I had it for maybe 15 years or so, I had to put a new solenoid on it.
So my thoughts are there are the same type available for liquid fuel as well-never looked into it- that are Normally Closed and open when energized. If electric is you preferred choice, this is what you’d look for.
Other issue, is if your T is 6v, might be harder to find, then the vacuum ones mentioned might be a better choice.

Or simply do as Jim said

 

There is also an RV dealer in waterdown I may try ..

 

You could do the choke cable idea and put a small micro switch that puts on a light when it’s pulled out .

“ Cost effective” and easy-ish

 

Could upgrade that to a buzzer that sounds when it's pulled out with the ignition off. You'll hear it when you're about to get out of the car, not just have a light you may miss.

 

Motorcyclists have been dealing with manual fuel pet****s for 120 years.. I would not want any pet**** inside the car but you may have to....$100 bucks for an electric valve..Geez, just remember to turn the valve on or off like us bike guys, it ain't that hard to do.

 

In the marine world we had to use an anti siphon
valve at the fuel pick up on the tank. It’s basically a ball and spring that had enough pressure that wouldn’t allow fuel to syphon if a line or fitting failed but the fuel pump would pull enough vacuumed to overcome the spring and allow fuel to flow. In your situation I’m not sure the head with the fuel above the valve would be enough to allow it to open but if it were me I’d give it a try. Seems better than the price of the electric solenoids. But still not better than a reminder note. This particular valve has a hose barb but I’ve seen them with npt on both sides.

Move your fuel shut off under your seat or in your saddle bag and see how long before you buy a solenoid , wasted a 100 bucks on worse things !!! Fireworks come to mind when the boys were young !!

 

One off cost of an electric solenoid is probably cheaper than a tow back home and gaskets plus fresh oil because the sump is full of fuel.

 

It's not that I forget often to turn off the fuel but the occasional time's I get sidetrack getting out of the car , costs me an oil change ,not to mention it's not good for the bearings .
If it were to hydro lock and bend a rod I soon would be wishing I had spent a 100.00 bucks on the old girl . One time could prove to be to many !!!

 

Seen this?

I found you another one at a discount

Me being the "King of Cheap" would take a punt on this [Only $17.99]
https://www.amazon.com/dp/B07X287BS...pY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU&th=1

This one has an indefinite duty cycle [it is a motorized ball valve that only draws current when opening or closing]

Not a problem..A responsible rider spends a minute slipping into the leather jacket and gloves and the helmet, turning on the pet**** is part of the preperation..New bikes , not all, have auto pet****s or none all all...
Don't want to spend 10 seconds fussing with a fuel shutoff in a vintage vehicle? Maybe you need to drive only modern vehicles without even an ignition key to slow you down..

 

This is not a constant problem of remembering to turn off the fuel , it has only happened a few times over the years . Nothing to do with being lazy or forgetful .Mostly get sidetracked upon getting out of the car .Only has ever happened at home .Friends or wife and even the kids need something ,get out of the car to help/see and fuel doesn't get turned off .

 

Ok......https://ussolid.com/u-s-solid-elect...MItM3y-JSt-AIV7vbjBx1klwJFEAQYAyABEgK6cPD_BwE
Note, not suitable for more than 8 hours continious duty...always check the duty rating

 

Also check voltage.
"Voltage: DC 12V ± 10%"
12V + 10% is 13.2V, with a healthy charging system you may have <14V.

 

We have a winner here ^^^
If I spend more than 8 hours continuously in an old Hotrod you wouldn't want to talk to me when I get out

Batteries are 12.5 volts so + 10% = 13.75 volts

 

Yes, but it doesn't say normal lead-acid battery voltage plus ten percent, it says 12V plus minus ten percent. Can't ***ume they mean normal battery voltage when they clearly say something else, and give a magin up and down from that. And besides, 13.75V is still below normal charging voltage.
No problem reducing the voltage to a level within the specs, and even if you don't there may be no problem, but it is a detail worth looking at.

 

Have you checked the needle and seat in the carb? It would seem that if they are in good shape you wouldn't have the leak.

 

At $12.99 its worth a try. [I would]
At $35.00 @wood remover could get the continuous cycle ball valve version
But this would need a SPDT relay to switch it off [divert it to off] These are really easy to connect and would make a good safety feature / theft deterrent on any car.

 

Ordered up a solenoid , will be here on Sunday .Will let you guys know how it works out !!!
