    I went to look at a 73 brown two door Mav today. Guy is asking $1200. It has 93K on the odometer and looks in excellent shape for the body (needs paint but no dents or rust) Anyway looked under the hood and it has a 250 six and I notices a large silver dial where the fuel filter should be. when I ask what it was, the guy says " Oh yea, that is a fuel pressure reducer. Ford sixes are known for putting out high fuel pressure (7-9 psi) and this reduces it to three psi. We are an old ford family and everybody knows this."

    Question: Is that true. First I have ever seen of it.

    Also if anyone is interested in this car (AT, power steer, man brakes, air cond (not working)). I llive in Redding Ca

    I've had just about every six Ford ever made in the 60's and 70's, from the 144's in the old Falcons all the way to the 300 in trucks. Thats the first I ever heard of it.

    Fuel Pressure

    Never heard of this either, I am wondering if maybe he did not install an electric fuel pump, or maybe has a bad needle and seat in the carb so made a quick fix??? Should be able to stand 4 to 6psi anyway. Did he tell you this car was driven only to church on Sunday's by a little old lady from Pasadina? Then again may be a legitimate reason I don't know about, I also have had all the Ford six cyl, as has Mavaholic, even a 47 flathead six, never saw a regulator on any of them either.

    Well thank you guys. That is what I thought. I could not fathom that ford engineers had made sixes for years and years but only this guy found out where they were all mistaken. If I buy it I will post a picture of the "fuel pressure reducer".

    Thanks again

    If your planning to buy the car act impressed rather than telling him he's full of bull. It will help you in the price negotiation.

    On my last Maverick,I built the I-6 250 with Clifford Performace parts thruought(and it was a very impressive rebuild).I was running a Weber 2-barrel carb and adapter,and under heavy acceleration,it fell flat on its face.Thru Cliffords message board,much like this one,I found the above to be true.With a Weber carb,they recommend running 2-1/2 -3 lbs of fuel pressure,as a stock fuel pump does push around 7 lbs.So ,off i went to my local performance store,and they told me the same thing.After installing the regulator right before the carb,I was running just under 3 lbs for best results.And for any of you I-6 fans looking for a little more ZIP,check out Cliffords website.

    The regulators were a common aftermarket part years ago. Used to solve flooding problems instead of doing the needle and float service.
