The Fuel Regulator
I
used a 5.0 CFI injection regulator They use an adjustable fuel pressure
regulator that fits the 2.3.
They don't look like they are adjustable at a glance. If you look at the top of
the fpr, there is a plug in the middle made of thin sheet metal.
Take a small sheet metal screw and screw it into that plug and then pull the
thing out.
Inside there is a allen screw-that is how you adjust the pressure, you can’t
see the screw in the pictures but it is inside that hole in the top.
The
CFI regulator does not however have a vacuum/boost port on it.
I drilled a hole in the side and taped it for a brass nipple thingy I had
laying around. You can just see it in
pics-Mine is facing the back of the engine
I tried blowing through it and some air leaked out the adjustment screw-which
has a hole in the center to vent to the atmosphere. So I plugged that with some
JB weld. I now have a working adjustable fuel pressure regulator for like maybe
$5.00 and it only took about a half hour to modify.
It
is adjustable from zero psi all the way up past 60psi (didn’t try to go
higher).
