Looking at the red outlined area....Is that a boot? For some reason I am missing that, and I suppose I should have something there.

 

It looks as though you have the boost bypass kit installed. If that's the case there should be a scew plugging that "boot".

On the otherhand if you truck is running OK I wouldn't worry about.

 

No, that pic is just an example. I have the boost dump solenoid plug disconnected is all. However my question is regarding the boot that is outlined in RED and has the arrow pointing to it.

Is it simply a boot plug, or does it lead to another vacuum line?

 

That is a vacuum line coming off of the fuel regulator. The vacuum line does not go to anything related to the boost bypass.

 

I think the question is ............. am i supposed to have a boot where there's one outlined in the picture???

The answer is yes........that is for the fuel pressure regulator.

 

Thank you. So a simple boot to plug/cap the line is all I need right? Could it have caused any damage by not being on there for an extended period of time? There is no telling when it came off....

 

That boot should be on there. It has NOTHING to do wth the boost bypass. That picture illustrates exactly what should be going on with the bypass kit. The pink line gets removed from the boot on the boost dump soleniod. The boot get's plugged. You put a new boot ont he pink line and tee it in where shown. The line on the fuel pressure regulator is not involved in this. Get a flashlight and see where the hell the line is, somehow, it got removed.

 

I'm sorry I even used that pic as an example now. I am not asking anything about the boost bypass or the bypass kit. Please see the updated pic!

I am only asking about the boot in the red outlined area (below the red vacuum line) with the red arrow pointing to it, which you say is the fuel pressure regulator!!

Is there a vacuum line that runs to it or do I need a simple boot to plug/cap the line?

Could it have caused any damage by not being on there for an extended period of time? There is no telling when it came off....

 

Dude,

Tallimeca is telling you exactly what you are asking.

There should be a vaccum line running to the fuel pressure regulator. Without it you will run rich at idle...

I dont believe the stock FPR's are boost-sensitive, so you are running at max fuel-pressure at all times since the FPR isnt reading any vaccum..

On the other hand, you will have a vaccum leak, so maybe the increase in fuel-pressure will account for the lean condition caused by the unmetered air leak...

Just find the line and reconnect it.

Please excuse my ignorance. I took a look but do not see any loose vacuum lines. I appreciate the replies. I'll have my buddy look at it ASAP.

 

After looking in that area for a loose vacuum line.... I found it and reconnected the end to the fuel pressure regulator. In fact it was a red line that appears to connect from the fuel pressure reg. to the manifold.

Now the real question is did this disconnected vacuum line cause any damage especially since the fuel pressure reg. end was left open for who knows how long?

 

Glad you finally realized what we were trying to explain to you!!!

As far as I know, our fuel rails aren't boost sensitive and the only thing that probably could have happened is it may have thrown your computer to make adjustement for it. I would disconnect the battery for about 20 minutes and reset the computer. If you did something bad, you would have know about it and so would we!!
