Fuel Shutoff Solenoid

[JCrank]

I'm just curious about the average life of the fuel shutoff solenoid on our trucks. I replaced mine about 7 months ago and it just failed again last week. The first one may have been the original. It was leaking around the terminal and the plunger was really rough. My replacement came from NAPA Echlin. It wasn't leaking, but was the only problem I've found so far. I've ordered two from Imported Car Parts site, but won't have them until probably Friday. If solenoid failure becomes a regular occurance, I'm leaning toward rigging myself a "manual" cut off inside the cab.

A local fellow ordered one from NAPA and it lasted the course of a few months. I re-replaced it with another and it has held for well over a year now. He has an extreamly modified injection pump... .



I have the original in my 92. Original for the replacement injection pump. It too is slightly modified.



The 1990 truck has lasted 309K and still going.....

My 93 only has just over 124000 on her. Everything remains stock at present. Thanks for the reply. The solenoids I ordered on line are supposed to be Bosch..... maybe they will last longer.

The one you ordered is probably from the link on here, i ordered one and they are Bosch, i carry my spare in the truck you can't beat that price.

I agree you can't beat the price. I did order them from the link here on TDR. They are supposed to be Bosch. Local NAPA sells for $126. each.

When I took the "new" Napa solenoid out, I found that the only problem with it was the rubber plunger tip had swelled causing the plunger to stick in the off position. I'm running mine without the plunger until my new solenoids arrive from California.

Four trucks, three solonoids, close to a million miles. No rhyme or reason to any of it. One has never need any attention. I use Bosch.

Any part numbers availiable for these?

 

[1stgen4evr]

The Bosch box has this on the label:





1 St/Pc



0330 001 015 (and smaller numbers) 000

then a bar code with these numbers below that

3 165143 089194

282 087610





Some of that ought to get the part.

It really seems that some of the parts/replacements we find need for over the years really are best when they come from the original source... .

For instance the one that comes to mind right away is the thermostat... aftermarket just don't seem to work well at all... but from Cummins, they work great and last.

Things like the start/stop solenoid is another one, if you can get an original Bosch unit they seem to last longest.

We have trouble with these items because we are cranking up the pump settings/pressures/fueling and they just weren't designed to handle that kind of work load/pressure.

There is another make of S/S solenoid that has lasted a bit better... . I can't recal the the name..... maybe, Zimex or something like that.

I bet one of the guys can fill us in on the name.

Fuel Shutoff Solenoid installation tip

For those of you that want to make replacing the Fuel Shutoff Solenoid a bit easier to get to on the side of the road. Here is a tip on what to do while at home ...



Bolted to the end of the pump head there is a flat piece of steel used to support the end of the pump. A portion of that steel plate rises above the pump head right next to the Fuel Shutoff Solenoid. . The portion that raises above makes it impossible to remove the Solenoid without first removing the plate.

A simple solution is to cut the portion that raises above the pump head off flush with the top of the pump. This will allow you enough room to swing a wrench easily .



The portion that raises above the pump head is not used on our trucks for anything... What it is used for is the throttle cables on other makes that the pump was also used in...

The one you ordered is probably from the link on here, i ordered one and they are Bosch, i carry my spare in the truck you can't beat that price.

And if you are stoped beside the road you can do the following. From my earlier post:



heavy hand method



--------------------------------------------------------------------------------



Since all agree that the bracket on the back of the pump is redundant for our application, I wanted to have it out of the way. Last time, I went to great pain to get the bracket off and trim it down. This time, I got an adjustable wrench and simply bent it toward the front and then back for about twenty five cycles and the top section of the bracket broke off even with the upper bolt. Like I said, a bit heavy handed but it sure as heck simplified the job. Moved the intercooler tube and the throttle bracket and voila, all the room in the world.



I had earlier said that it reqiuires a 15/16 bent just so. Well, that ain't so. It is bigger than 15/16. Got to be metric so I ground my special wrench to fit. I am certain that the one on the 92 was removed with that wrench but it simply would not fit the 93. Took less than an hour to complete.



Any way, she fired right up without any bleeding.

a chisel and hammer works wonders. the cap has an o ring under it. one to two taps and the cap should spin off by hand without removal off the plate. The city diesel boys showed me this the first time I replaced my solenoid. after the third time I yanked out the plunger and installed a manual kill
