Hey Folks,

Went to the shop yesterday and for the umpteenth time found the fuel valve left on and a lovely fuel spill. I am fortunate that I have not filled the crank case YET. Anyhoo, ever heard of someone puttin a 12volt solenoid valve in the fuel line that is activated by the key switch? I am going to do some looking around for such a valve and entertain the thought.

Anyone got a line on this?

Noel

We"ve been installing/ selling 12V Neg. ground gas shutoff"s for $25 plus shipping for several years now, haven"t had any complaints yet. They look like a small inline gas filter. 920 295 3278 or email, Dale

Dale,
Is a toggle sqwitch included with this? Do you have pictures of unit. I would like to know if it is similar to the one I have on my truck. Been on 19 years and works great. How much is the shipping?

The gas shutoff is 1.5" dia., 2.5"long. 2 wires to be attached to the ignition switch or however you wish. $5 for shipping, Dale

I still have a gas cutoff solenoid switch on my 87 dodge van. It gets activated by a secretly placed toggle sqwitch. The idea was to prevent you car from getting stolen. My brother the plumber had his trucks stolen more than once. After he placed these solenoids in, they tried to steal them but ran out of gas after two blocks.
I bought mine from JC Whitney back then. They don't sell them anymore and I have't been able to find another source. I have a 1971 Continental Mark III in the garage and I need one of those myself. I can tell you they work great because I forgot to turn the switch on many a times and got stalled real quick.

Clean your carb and fix the float valve works real well.

Another suggestion which solves your problem at zero cost and is (in my opinion) better for your engine. I also fly and when you're ready to shut down an aircraft engine, you don't turn off the ignition, you withdraw the fuel by going to full lean on the mixture control. Years ago on my 8N, in copying this, when I'm done with the tractor chores, I get off and turn off the fuel. It generally runs a couple minutes, which is a nice "cool down" procedure, and uses up all the fuel in the passages and prevents leakage into the crankcase. Only two things to remember, after it stops, then turn off the ignition or you'll have a discharged battery, possible burned points, and when you are ready for the next chore, the gas has to be turned on or it won't start. I've used this idea for a long time and it has been beneficial. Also, no leaks on the floor where I keep my 8N, ten feet from a water heater with a pilot light, so that's smart, too.

Yep. I agree, Jim. I do the same thing. But the inexpensive answer is....habit. Form a good habit and it'll stay with you. EVERY time after you get off the tractor, turn the fuel valve off. EVERY time before you get on the tractor, turn the fuel ON. Simple. Heh?

I use a Bobcat fuel valve - $62 bucks, a few more for fittings. Works good.

Theres a John Deere fellow That has a page on restoration tips name Frank Boerger. He has a lot of good info on electrolysis and stuff. But down near the bottom of the page he has an article on using an oil pressure switch to turn power on and off for ignition coils. I was wondering if you could use a similiar setup to activate your fuel solenoid...heck even your coil if you forget to turn the key off. Sounds like an interesting project

You could do it with a 'murphy' style oil switch/sender/gauge.

It has a manual bypass button you would hold to energize fuel solenoid and ignition coil.. Once oil pressure came up the switch 'latches' and you let up off the bypass. If oil pressure drops.. it unlatches the switch, therefore in this case.. cutting power to the coil and fuel valve in case of a stall, loss of oil pressure .. etc.

To shut down inthis case.. you would have to manually starve it of fuel. I would also reccomend an emergency kill switch.. a push button/momentary kind with normally closed ( NC ) contacts, that open when you push them. Install this in line with the feed for the murphy switch.. hitting this button then kills ignition and fuel, kills engine.. oil pressure drops.. and murphy switch resets 'ready' for next use.. etc.

We use these on big expen$ive pieces of equipment as low oil pressure auto-shutdowns to save 10k$ dollar engine rebuilds on those big diesels.

I've seen them -retrofitted- on old diesels that didn't have a fuel solenoid in the injector pump. One was on an old ford diesel I believe.. after setting for long periods diesel would get into the engine.

It should be as simple as plumbing it inline with the fuel flow, and powering it off of the ignition. Keep in mind that when you turn the ignition on.. you will have to let it fill the carb bowl for a second if it was starved down by manually closing the sediment bowl valve to leave a 'dry' carb.

I probably also wouldn't put this system on a machine with a magneto.. even with a charge system.. the nice thing about a magneto is that it will run with no external power.. the fuel solenoid would kill that idea.
