Confused 4bt owner, needs fuel shut off solenoid part number

1515 Views 14 Replies 5 Participants Last post by  marshallnoise
I have a 85 Silverado with a 4bt swap, driving down the road this weekend and it just shut off, like someone reached over and turned the key off. I am pretty sure my fuel shut off solenoid failed and have it removed (finally). I read a Bosch part number of 0330001915 on it, but not getting that anywhere on the inner webs. In searching around a bit I am only finding parts for a 89 and newer Cummins, but swear mine is a 1986 per the attached, any help is much appreciated.

As a aside, what is everyone's opinion about going with the delete option?

Curious, have a hard time reading that serial number in your photo. Can you post what it is?

Are you asking me about my engine serial number?
My experience with Amazon ones is they suck. Small sampling though. I would definitely suggest you get a higher quality one. I heard some VW solenoids work too. Also, carry a spare in the truck.
Yes, you posted a photo of your engine ID plate but I can't see the serial number clearly. Appears to start with 44 and then it's harder to make out.

Yes it starts with 44166980
You are correct about the build date. Your engine was built June 26, 1986 at the Consolidated Diesel plant in Rocky Mt., NC. That was the primary building plant for B and C series engines. Your engine is a CPL 0767 which was a common early model. One unusual feature of that CPL was an odd exhaust manifold with a compound angle. It tilted the turbo away from the block and and aims the exhaust at a downward angle. To my knowledge no other CPL used that manifold and Cummins discontinued it due to the fact it seemed to cause premature bearing failure in the turbo. Those engines were commonly used in the Ford E350 vans. Below is a photo of one of those. You will find later produced engines with the regular rear drop manifold. Original injection pump on the engine is Cummins part 3908191. The shutdown solenoid listed is part 3903575 which is priced at $318.75. LOL. That's why most go with an aftermarket replacement. On the Bosch part number 0330001915 you listed, I think you may have one digit incorrect. The part number should be 0330001015 and here is one listed on Amazon for $19.43. https://www.amazon.com/Friday-Part-Solenoid-0330001015-1988-1993/dp/B073SP7QNQ They do come cheaper if they aren't in that pretty Cummins box.

Wow - what a lot of great information, thank you very much! I am going to delete the shutdown solenoid and go with the manual shut down method. Looking to set it all up early next week.

I would like to drop a brass plug in the place where the solenoid goes, something with a Allen head or something easier to get a wrench on, but not sure what to put in there, if the tapered end with that o-ring needs to go back in the hole?
Just remove the plunger and spring. Reinstall the solenoid (with O-ring).
Like Russ says, you just take your old solenoid and remove the little plunger and put the gutted unit back in the hole. Then get you a push/pull cable to connect to the little lever for operation. Tractor supply sells one for $16.99. Many diesel farm tractors had mechanical shut down. https://www.tractorsupply.com/tsc/p...8TIYYSOLYiZIdiXoeOpvKNOtQZn2LzFhoCIsQQAvD_BwE Or if you want cheaper Dorman part 55196 or 55201 are universal cables. Having your engine serial number you can go on Cummins Quick Serve online and see every part of your engine as it was made. Yours came just like the one in the photo I posted so it likely was in a Ford van. They were about the only ones that used that belt driven vacuum pump setup.

That is what I will do, I picked up the pictured cable today and will put the stripped solenoid back in.
