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

I had this happen to my 90 Fox. The regulator is a sealed (supposed to be)
unit. It has to be replaced. 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.

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.
