ok thanks for the pics i did take off the right part but have cfome to the conclusion because there is no glass ball in mine i guess that is my problem with my hard to start problem with the nose up but with the nose down starts up fine

 

[tankie88]

i cleaned mine up after probs and fitted a in line filter and hey presto....no probs

 

[beanman1]

does anyone have the part number for the valve trying to find a new one and no part store here seems to know

 

[Warthog]

The parts number is GM 14067420 or 23183.

I have never checked but you should be able to get them from any Stanadyne parts house. I doubt you will find it at NAPA

well i went to the chevrolet dealer today to get a new check valve and i was told that it was a discontinued item and no longer available through gm i am in need of one real bad is there any member out there that has one for sale

 

[lavarok]

A pump rebuild shop will have the part. Accurate Diesel in Orlando is one such shop.

It gets clogged by a plastic washer in the IP degrading as the chunks get bigger the worse the performance finally it just stops running.

i have the updated pump that does not have the plastic washer the check valve on ine is missing the glass ball so i need a new one

OK, I'm a little confused here. Is the glass ball in the bottom of the piece on the right in the attached picture or is it in the piece on the left?

The piece on the right is clean straight through. Nothing in mine.

The piece on the left has a valve I can push on and it will open up allowing carb cleaner through, but there isn't a clear glass ball anywhere in it. I tried taking a picture of the top and bottom of it, but it didn't turn out very well. The piece that I can move upward is more like white plastic.

So am I missing the glass ball? This is giving me a headache.

 

[lavarok]

It would be in the piece on the right. Someone prior to you must have punched it out.

The pump shop where i took my pump to said that the drive ring that is breaking down will eventually break the pop rivets and the motor will run away. im gonna try to post pick of this when i get it back.

I'm at least the second owner. I actually bought it from a guy on here and he said he had bought it from the army base.


So if the glass ball is supposed to be in the piece on the right; and all the gunk I keep cleaning out is in the piece on the left, then does that mean the IP is getting ready to go? Last night would be the 4th time I've had to clean it out. It's been about a month in between the 2nd and 3rd time I had to clean it.

It's ran fine today to work, we'll see what happens when I try to go home again tonight.

I believe I saw that someone had posted that you can't get the return fuel valve from Chevy anymore, but you could get it somewhere else. Perhaps I'll try to buy a new one.

Is the replacement check valve a steel ball? When I had my IP rebuilt I swear the fella said he used an upgraded check valve for the return line.

I think you will be needing a injection pump soon. I punched out my ball I am going camping this weekend with it then its time to get a iinjection pump

Bringing up an old topic, but this past Friday the return fuel valve got so clogged up it killed the motor. I let it sit and came back after work, cleaned it up and drove it home.

I let it sit at my parent's house on Sat. and Sun. I cleaned the valve again and drove to work today. On the way home, I noticed it was starting to run like that valve was getting clogged again.

I keep reading multiple posts about how all this means that the pump is going bad or going to go bad. However, I don't understand how the seals in the pump can be clogging that valve, because isn't the fuel going the other direction? I keep getting gunk in the bottom of the valve, not the top where the glass ball is supposed to be.

Is it a consensus that it is the pump that is going bad? I removed the hose that connected the valve to the hard lines coming from the injectors and it looked clean.

The gunk in the valve isn't metal and it feels soft to the touch. Of course it has been soaking in diesel.

I don't have alot of money and this is my only mode of transportation. So far I've been carrying my tools, carb cleaner and a paper clip with me to clean the valve out when I need to.

I need some direction/advice here in what my best course of action should be.

Just jumping in here and have never done one but I would bet the one on the right is just a brass nipple fitting. No glass no balls
