I had to put a pull cable in cause my FSS went bad and I hate it. Just seems rigged and I dont like it. I have a new fss on the waythat should be here in the middle of the week. If that dosent hold up I gotta do something else cause I cant stand the pull cable. Has anyone done anything else different? I was thinking about an electric actuator or something like that.

 

we have a string in our boat for fuel shut off, but i dont think thats what you were looking for hahaha

 

not exactly lol

 

buy some bigger injectors or turn down your pump.

 

Do the little mod to tip on the shutdown solenoid. Been working good on our 93, maxed out pump stock injectors.

 

When you lay into it, don't pull up your foot so quick. The diesel back washes a bit and that is what destroys it.

Go get a MAck model R (I believe) engine shut down cable.

 

He doesn't want a cable at all.

There's the fix to this, you just have to shape the rubber tip on the shutdown plunger into more of a round shape and get rid of the jagged edges, it's just rubber so sandpaper will do.

 

Yea i will reshape the new one before I put it in

 

i think there was a post on 1stgen.org where a guy made the plunger out of the same material that screw driver handles are made of.

 

You could put a pull solenoid from a "C" engine on it. It would mount to your manual shut down lever. They have three wires, one is a ground, one is "key on" power (hold winding), the other is for the "pull" winding (this would be wired to the starter trigger wire.
You would need to have the lever on the pump work in the opposite direction that it does now though. What I mean by that is, as it is now, the spring action keeps the pump "on". This would need to be changed to "off" in its normal position.

 

Any cummins machinery used that type of shut down solenoid that trendz speaks of. Its simple really, even a door popper or window lock solenoid would work if adapted right. You could leave it how its orientated now and have a momentary switch for when you shut off the key it pulls for 3 seconds, then releases.

Just throwing a few thoughts out there...

 

What about a power door lock actuator?

Edit: NO FAIR

 

The first thing that comes to my mind is an old "idle up" solenoid for a carburator when the a/c was going. But any type of actuator would work as long as you build the bracket right, then just simple wiring from there. I've thought of doing this, no only to get rid of the pull cable, but as a theft thing also. Good luck, and I know what you mean by "it feels rigged".

 

Being more used to big trucks than little ones, I purposefully installed a locking kill-cable in my truck; it is one of my more favorite modifications.


With a little fore-thought and design ingenuity, there is definitely nothing "rigged" about a good manual kill-cable; plus, there's the COOL factor.

I have everything ready to completely do away with any need for the switch-key at all; I just haven't taken time to complete it.

 

If you have an onboard air supply on your truck you could install a small air cylinder to actuate the shutdown lever, it would have plenty of power, you could actuate it through a solenoid valve and as simple as a push button.

I have used small Bimba Cylinders on some of my projects.

The old Flxible Transit Coaches I used to work on had a 6V-71 Detroit with a 2-speed transmission and when the transmission shifts an air cylinder closes down the fuel rack and stalls the engine for an instant.

Has anybody ever tried to replace the soft tip of the FSS plunger with nylon or another fuel resistant material?
