CIS-E leaking fuel from differential pressure regulator!
Hello all,
Yeah, there is fuel spurting out of one of the four tiny holes in the differential pressure regulator that screws onto the fuel distributor. The four holes, one above the other, look like they're supposed to be there. The top two are sealed with what looks like epoxy, and the second from the bottom is leaking fuel whenever the engine is running or while there is pressure after engine shutdown. Do I need a new regulator? Is this odd? Is there another more sinister underlying problem? Thanks Theo |

They're pricier than they look too. I think I paid like $125 for it. That said, It's a 5 minute job to replace it. Just 2 screws and a wire to unplug. Save the O-rings from the old one unless they look damaged. ....Sean. |

Thanks. That's what I was hoping (except for the "pricy" part). Right now
the only thing that suffers is gas mileage, but I'm guessing that the fuel pressure accumulator will be unable to hold pressure because of this and hot starts may become a problem down the road? There's also, of course, a school of thought that says you should minimize the number of components ****ing fuel around under the hood... The apparent sealing on two of the regulator holes looks so cheesy. Theo > I had this happen to my 90 Fox. The regulator is a sealed (supposed to be) > unit. It has to be replaced.
