The sole purpose of the regulator is to maintain the proper fuel pressure to
the carb(s). So for it to wormk, it must be installed between the pump and
the carb(s). If after installing the regulator, you are obtaining much
better mileage, my guess is that it is due to the elimination of a loss of
fuel fhrough the carb overflow. If the fuel pressure is too high , it will
overdrive the float valve and the excess fuel will drain out the overflow
pipe, reducing your fuel mileage and causing the smell of raw fuel, if not
also causing paint to be removed from the frame where the raw fuel drips
down.

smooth job. They pop-riveted the rear 3 center button snaps, but then again,
I was only able to provide 2. It works. A couple concours points off, but I
don't mind. Now I can drive it around in the rain. I just gotta get the
plastic shells on.

fuel pressure regulator, despite advice not to from previous correspondence
on here.

helping on fuel economy. While I didn't install it on a full tank(more like
3/4ths full), I'm already at the 140 mile mark, and there's plenty of gas
left. Prior to the pressure regulator, it would have been at empty at 140
miles.

I'm still not sure of the logic of the instructions saying to install the
pressure regulator between the fuel pump & carb, but I did regardless. No
fuel leaks.

> The annoying part is I have a minor oil leak where oil is collecting up on
the lip of the valve cover! It's gold colored, but I cant' explain how oil
is getting "up" on there. Is the valve cover cap bad? It seemed fine when I
took it off & examined it.

is still an ongoing experiment. I just wish they were a bit longer(like the
screws I took out) so I could fit the mityvac hose on it better.
