Third time's a charm??
 

So, this is the third time I've made this post in 3 forums now. It's been made in FTE, Diesel Bombs general IDI category and now I'm here. Hope someone can toss out some input. My IP is leaking from just below the torque screw. It's coming from the fitting under the red plastic cover shown in the pics. From what I have researched, it's the guide stud which holds down the metering valve assembly?? I'm sure there's a seal on the guide shaft but from what I can see in the stanadyne drawing, you can't pull the guide stud without things coming apart on the inside. I guess my question is, can I pull the guide stud and try to re-seal or is it holding a bunch of other parts in place, that will come apart if I take the guide stud out? Just want to fix this damn leak. My main feed line from the filter was leaking also and I bought the braided stainless one from Mel and that problem was solved but this one is worrying me. Any input would be great. Thanks in advance.

I don't would not advise replacing just the seal as there's many things that can get altered and lead to a premature failure. That being said it's entirely up to you. It is possible to fix the seal, but once the pump starts to leak failure usually follows.

I know the pump is going to need to be changed soon. Just wanting to stop the leak for now if I can. Does that red cap play a role in what's under it? Is there a bleeder valve or something under it?
Thanks for the reply.

I'll have a look under mine since the pump is off, post back when I find out :c:

That would be great. Thanks

seemed to just be an adjuster, but could not get mine to budge what so ever. :humm:

After looking through everything I could find, it's a discharge fitting, which is help in place by a stud guide, and looking behind it within the pump, it seems to be going through the governor spring, and hold it in place. I could be wrong though, someone else should chime in soon.

That's about what I saw on the drawings from stanadyne. Just need to know if I can back it out a little and try and seal it off somehow or if I pull it all the way out if things will fall apart in there or not. ha ha. Thanks for the info. :c:

I wouldn't suggest pulling it out, but there is a seal in there. I will try pulling mine out and let you know how it goes :tu:

cool. if I can even back it out just a few turns I can get it sealed. thnx

Any luck with this one guys ???
