HPFP irratic reading at high RPM

i did.

 

i ordered a new pump. ill put my internals in it. the connector on my spill valve is broken anyways. i just hope the spill valve is the issue. like i stated before. my internals look great.

 

You can ziptie lasso the current one but that shouldn't be a problem unless its coming apart

 

It's not.like falling off or anything. Mayne the spill valve is simply bad?

 

yes i did

 

Seems unlikely. What are you going to do if swapping the HPFP results in the same issue?

Edit: Also were the internals scored or marred in any way?

 

I have no idea.

 

i didnt see anything that looked scarred up or anything on my internals. ill get a pic of them when my new pump comes in and i replace that. any other ideas? another 400 bucks in internals would suck being mine are only a little over a year old.

 

If they are scored you can probably get them warrantied. I did that with my Autotechs.

 

ill check them out again when i pull it back apart

 

Here's my internals. The only thing I see is the dark band in the middle of the shaft. I can't feel it but I can see it.

 

Tough to tell with the glare but looks like you might be getting a hot spot on the shaft

 

Looks likenit to me. Why?

 

Why is it happening and would that cause my issue?

 

If you put the piston in the collar dry, does it move easily or is it rough and hitchy? They must be perfectly clean when testing (use lighter fluid for this).

 

It dosnt feel bad at all. Really pretty smooth

 

As long at there's a little "moisture" it's smooth. Dry dry.. it's sticky

 

That's a problem then. Likely time to warranty.

 

Ok. I contacted them they said to send it in for inspection. It seems likenits in the piston not the shaft.

 

You mean the collar. Could be the collar that is fucked up, cause that doesn't get the DLC coating.
