Fuel shut off solenoid

[ARedetzke]

My truck wouldn't shut down with the key today when I got home from the car wash. Did some searching in the archives, and removed the shut off solenoid, cleaned it (no metal shavings), and replaced it. Still doesn't work. I did notice that the rubber tip on it was chewed up. There was one post in the archives about this, but no resolution. Does anyone know if I can get just that rubber tip? Also is there anyway to test that the solenoid is actually trying to engage? I hear they're kind of expensive.

TIA

I just replaced mine today - it's been acting up for the past week. The tip had a small nick in it - all seems to be working now. I've carried the spare for a while now - just in case. Some have gutted it and run a cable to the manual shut off lever. Since I like to carry a spare I will pick one up at Cummins NW tomorrow so if you need the P/N I can get it for you.

That would be cool. I'm assuming you're talking about the tip and not the whole solenoid? Seems like every time I call Cummins around here they have no idea what I'm talking about, no matter what I'm trying to order.

I just went throgh a similer situation with my truck on friday.

Pulled my soleniod and try jumping it with a wire from the positive post on my battery and grounding the body of the soleniod. It did not retract or pop.

called Cummins northwest and tryed to get it but they do not have it in stock. Anyway that wasnt my only problem, the ve had died so I have a new pump on order.

Any way to make a long story(sorry) short the tip on my old soleniod is still good if you want it pm me your info and i'll mail it to you

I have seen some problems with the Bosch rubber tips. My origional tip failed about a year ago. Shortly after I went through 3 more. The replacement tip looked slightly different from the stock unit. It seemed a bit softer, and the bowl was more pronounced, with slightly less material around the sealing edge. A couple of customers also had this issue. One lasted less than 100 miles. Fuel passes by the plunger at about a 45* angle in the hydraulic head. So, all of wear is focused on one spot near the tip. I am guessing the reason that the newer tips are failing is because there is slightly less 'meat' and cant withstand the fuel pressure/flow. Zexel also makes a plunger for our applicaton and looks more like the origional tip, and seems to be working quite well. I have talked with a local pump shop that has also seen a slight increase in failures. There were going to contact Bosch, but I have not heard back from them about that yet. For the time being I am usingn the manual lever with a cable. I will probably try the Zexel unit soon.

Good info Mike, that will definitely help the guys who are munching the solenoid tip... thanks bud... !!

Man, what is it with these fuel shut-off solenoids this week. I just replaced mine last week (see thread "Wew, It's not the pump"). Mine had a large chunk of the tip missing. SOunds like at least 3 others this week as well.



I don't feel too bad about mine. It was the original plunger so it was due. I just hope the new one last half as long. From what Mike is saying, don't hold my breath!



SO, My question is "Where does that piece of rubber that breaks off go to?"

Went down to Cummins NW for some oil filters for another application and ordered a "solenoid, fuel pump" for my '93 - they are on back order price $123. 25.



Mike I would be interested in that Zexel unit if you can get me a price and/or order one for me - PM me or post with the info.



Looks as if the higher HP numbers might be creating a reduced life span for these solenoids.

Bob the newberg napa has a soleniod in stock if you need it right away(110$)

They ordered it for my truck but since my new pump comes with one I don't need it. They said they keep it in stock till they sold it.

I don't want to make you feel bad but you can get these solenoids for under $50 from volkswagen. It is the same solenoid they use on their pump. Last I heard, they were something like $42. Alternatively, get them dirctly from a Bosch pump shop. Cummins gets them from Bosch and they are going to make their money off of them. Might as well cut out one more middle man. If anyone needs the part number, I will post it tomorrow as I'm at work right now.

please post the VW part number and the part number or contact info for the Zexel tips. I never knew you could just get the tip.

 

[CDegner]

The Bosch part number that I jsut installed is 330 001 015. Works great.



Here is info from VW:

Fuel Shutoff Solenoid

0-330-001-040

36. 00 from

Valley Wagon

Carson City NV

Phone Number 775-882-2350



I don't know what the difference would be between the 2 slightly different part numbers. I have a VW pump and the solenoid looks identical to mine.

Has anybody actually tried this solenoid, or does it just look as though it would work, and we need a guinea pig?

solonoid tip and metal fragments

Where does it go? I guess I am driving on borrowed time. I had the 92 quit at a red light and wouldn't go at all. This was several years back and at the time I wasn't on TDR. I hauled the truck 200 miles and got a solonoid from the local Bosch shop. I have run the truck another 100k miles and don't have a clue as to where the small metal fragments were coming from or where they wind up. I had no notion that there would ever be a need for the plunger so it is long gone.



My failure was not keep running but rather no running. I posted on the solonoid from the local Bosch shop a couple of months back and the prices I have paid are under eighty dollars. The price on the VW unit sounds very good. My guess is that they will be interchangable. I certainly would not hesitate to try one.

And to think that I gave away a VW pump a year ago... with a perfectly good solenoid.

Oh well...

 

[BushWakr - RIP]

The metal shavings go thru the pump and chew it up eventually. . especially if there are alot.

The rubber bits seem to just ride into the sunset and are never heard from again... usually causing no problems at all. Go figure. .

I'm going to try it this weekend. I'll report back on my findings.

 

[guava]

Ok, I tried to pick up this part from the local VW shop and they said it wasn't one of their part numbers. Can you give me any further info about the year and make VW it matches up to.

I would suggest calling the dealer listed with the part number. They are the one that provided the part number to someone on DTR.

Ok, I got really tired of shutting down with the cable when my plunger went bad.

So, Mr. Plunger and I sat down with a cold beer and we discussed the whole failure thing. We both realized the rubber sticks out way too far into the path of the fuel and that is why Mr. Failure rears his ugly head and takes out a chunk of the rubber.

Well, being the kind of guy I am and just happen to be in possession of a mini lathe, I took . 080" off the end of the rubber, replaced the spring with one . 080" longer, and viola!! one working shut off that "should" not go bad again because it is "behind" the flow of fuel.



Ok, that job's done,, on to the next.
