Flathead, single 94 carb, stock mechanical fuel pump. Does it matter if the regulator is level (adjuster screw up) or can it be mounted on the side (adjuster screw facing forward). Either I'm going with a regulator (around 2 psi) or going to stack fuel stand gaskets (which I don't want to do). Leaks bad after shout down from throttle shafts (and bowl a little), got way worse (dribbled slightly before sometimes when hot) when I changed the fuel pump stand gasket from a thickish one to a thin sheet of paper one.
No experience doing it, but I think on the FordBarn I recall folks shortening the rod? a little at a time.
There are n stupid questions if you are really trying to learn. Admitting you don't know and soliciting information will get you positive results. There are, of course, foolish questions from people who don't really want a real answer.
Thanks everyone, I was thinking it was ok since it's just a spring and diaphragm. But having not used one before and a quick Google search was no help, I ****ed it up and asked my stupid question here .
Regulators and moderators, they can do their job standing, kneeling, sitting and prone. Not real picky.
I have never checked my fuel pressure on the flathead, but should the pump not put out the correct pressure of around 3 - 3&1/2 lbs, for the’94 ? What is the advantage of running a regulator ?
Mine wore out to the point that it stopped working altogether, so I shortened it some more and tapped a thread in it and put a bolt into the thread with a lock nut and now I have an adjustable fuel rod. Later I read on here that the fuel rod is made of hardened steel, so I don’t know how long mine will last…..
Run your regulator no more than 2 to 2-1/2 psi. Yes you can run them in any position. Residual pressure after shutdown is very common on those carbs and they will leak. An option would be to install an electric pump that has a separate switch. Turning it off before turning off the ignition will alleviate this residual pressure. I’ve had great luck with these regulators.
I put the regulator on, now it's at 2 psi and I lowered the float. Seems ok now, I'll drive it tomorrow to confirm (might need lower the float a little more).
Some of the new ones (from early 2000s to now) put out too much pressure in "stock" form (from what I've read). If you rebuild on old or original one you should be ok, but if you're not having problems that's good.
As I used to tell people that worked for me, " there are no stupid questions, only stupid answers." If someone asks a legitimate question, they deserve a legitimate answer. Perhaps they really didn't know, or couldn't understand what was said, or shown.
