Hi guys, I have a big problem on my FD I hope someone can help me..

I'll put an aftermarket Fuel pressure regulator on my 93 fd, but when I take out the Stock one, I repair that this one have 2 vaccum line, I never see any car with 2 vacuum line.. Which line did I use for the aftermarket FPR?? Where goes the other line??

I let a foto here of my Stock FPR for guys see:

Can Any one help me??

Thanks

 

I can't see the photo but I suspect that you can just have a vacuum line from the UIM to the FPR will be fine.

 

Do you have one like in this thread?

Sorry for the foto

Yes thats exactly that, the right FPR with 2 vaccum line..
Do you know what line I attach on the aftermarket FPR?? What did I d with the other??

 

EDIT: The foto of my FPR:

That is a weird looking regulator. That came off your car?

 

Yes It's weird to me too..

Can anyone help my, it's Urgent...
Thanks

 

It is a j-spec FPR. If you have installed an aftermarket FPR just connect is to a vacuum/boost source on the manifold. The stock FPR was routed through a solenoid, you no longer need to do this, so just cap off both the sources for the original FPR.

 

So if I inderstand it wright, the stock FPR is connect to the fuel pressure solenoid and to an other think, and the fuel pressure solenoid is connect to the manifold, I just have to connect the aftermarket FPR to the manifold, so I eliminate the fuel pressure solenoide and tap on the other vaccum line..

Just for me, where goes the other line??

Thanks

 

In the case I said With to vaccum line directly connect to the manifold, the fuel pressure solenoide will be unuse, but like It the ecu don't be acuse ERROR, because the solenoide don't send information to the ecu??

 

You removed the two lines, you would have to tell us where you disconnected them from.

As long as you leave the electrical connector on the solenoid then the ECU will not see a problem.

 

Just one more doubt, the vacuum line who connect the solenoide to the stock Fpr, have a T and separade te vaccum line to the Fuel pressur solenoide, and an other solenoide, don't have problem to leave that vaccum line open or I have to tap on all the vaccum line that I don't go using..

Sorry and thanks...

 

European spec fd's have two solenoids for the FPR.You can use a T to connect both lines going to the aftermarket FPR.

 

But What I indderstand I don't have to connect the Aftermarket FPR to the solenoid, I Have to connect directly the aftermarket fpr to the manifold, and tap on all the vaccum line who I don't use...

 

Don't bother with that, just cap them off and run a line directly to the FPR from the manifold.
