I had the same problem today as I was about to start mine. Huge fuel leak between the pressure regulator and the aluminum block. Make sure you use the oval shaped rubber grommet from the old engine that goes between the plastic fuel regulator and the aluminum block (previously used between the regulator and the fuel rail). I didn't have the adjustable regulator on my 1.9 and had to buy a new one. No where in the manual does it say that you need this grommet, and it didn't come with the new regulator.

Yep. That was it. Thanks. Car sounds great. Can't wait for the season to start. Although it will be a while here in the Midwest.

I did not have the regulator before either. Did you get the new grommet from hardware store, or did you have to go back to SCCA |

Great to hear that you found it and it's running. Sounds pretty snotty, doesn't it? Quite racy. I had the same problem with my O2 sensor that runs to my dash A/F gauge -- didn't quite have the plug clicked all the way together. Drove me nuts for a while. |

Tony:
Thanks for your post. I'm still at the stage of fighting through correct motor mount locations to get the engine in. With as much difficulty as I've had with that, I'm just SURE that your problems will be my hurdle once I finally get the engine in. At least now I have some problem definition to be prepared for and a lot of expert advice on troubleshooting! Joel |

I discovered that my fuel regulator is leaking between the regulator and the base as well, just as described in this post. However, I don't know of this oval shaped rubber grommet from the GEN2 motor. Can someone provide a little more detail on what this is, where it can be found, and where it goes on the new regulator/base? |

It may be the one shown in the image to the right in this photo:

Sent an e-mail to Mike Davies to inquire. He said there is a seal from the old (GEN2) fuel pressure regulator that needs to be used on the new regulator. There are two ports on the new one, one for fuel in (high pressure and with O ring) and one for fuel return (no pressure). The seal from the old regulator needs to be used to prevent the return fuel from seeping out. Attached is a picture of both the O ring and the old seal from the old regulator. Mike said to be cautious with the old seal because Ford doesn't make them anymore.

Try searching for this part: Motorcraft CG590 Pressure Regulator Seal
About $18 on Amazon but may be able to order at your local auto parts store... Bob Breton - SRF 51 - San Francisco Region

Got the seal out of the old regulator that was still on my GEN2 motor and installed it in the new regulator. That stopped the leak. Thanks Bob for the pointer on buying new ones on Amazon. Will probably buy one 'just in case'.
