Ken ct you were right

Last weekend I installed a Ken Ct rebuilt carb on my 46 conv.Ran ok,idled a bit erattic,and I noticed gas on cover of the carb.Called Ken and we discused the problem and we narrowed it down to that it was most likly the China fuel pump putting out to much pressure.My spare pump was also a China job,so he sent me a rebulit pump.PROBLEM SOLVED!!!!!When will we learn the lesson about the China stuff.Thanks Ken. Phil

Thank you Phil,some will never learn,they buy by price and China pumps are a little cheaper BUT TOTAL garbage.Happy motoring Phil. ken ct.
 
You can lower the output pressure by adding gaskets to the pump stand. In any event, a pressure regulator is a good idea regardless of where your pumps were made.
 
What pressure regulator do you recommend. I have 2 old Filt-O-Regs from the '60's that were never used, model S-200 & S-300 and a Purolator Pro-Fuel # 54 adjustable, 1/2 to 5 1/2 # in origional packaging. I am concerned about using any of them due to new gas. Any comments or advice. Would be use on a 21 stud engine. Thanks
 
Use a Facet pump, about $33.00 from Aircraft & Spruce. Made by Puro-later in Elmira NY, USA, both 12 & 6V models. Built in regulator. Found out about this aircraft pump right here on Fordbarn. Pay attention. No need to buy China crap.

How would you regulate the pressure with a faucet pump?They are set at a predetermined pressure from the factory,at least the ones I have worked with are .I wonder if all the vehicles with fuel pressure regulators have the wrong pump on them .

Mike, I have heard this before, but I think you will find that if you study the pump. That restricting the stroke of the pump effectively reduces the VOLUME delivered. The delivery pressure is solely effected (caused by) the big spring, that is found under the diaphragm.

.Trainguy and KenCT, Ford has recommended (specified) different delivery pressures for the range of carbs it has used over the years.
Before you rubbish the Chinese made pumps for delivering too high a pressure (and Ken, you might well know, and they might well be rubbish for other reasons), Did you check the application and delivery?
Ken, Maybe you have done so already, but can you explain with some factual details as to why to stay away from the chinese pumps.
Trainguy, Which carb are you running? and what delivery pressure is specified?
What was the delivery pressure of the Chinese pump?
Nobody likes bad press, and undeserved bad press is worse.
Surely free speech carries certian responsibilities.

BTW, I have no Chinese affiliations what so ever.

Train man isn't the only one thats cured a flooding problem by replacing the China made pump with a usa rebuilt with an original diaphram spring.Also the waffer in the valves is coated with somekind of rubberized material and the corn-gas eats them up pretty quick and poor quality rubber diaphrams themselves. All ford pumps will work fine with anywhere from 2-3# pressure.Ive done hundreds of pumps over the yrs. Info is from real world experaince with them/ ken ct.

Why not correct the problem instead of using band-aids on it. ken ct omo.

But Ken, the OEM Ford pumps were designed to put out more pressure than the stock carbs could handle. Why? I don't know; perhaps to allow for some wear and tear on the cam, the pushrod, and the pump itself.
 
KenCt. Thankyou for the explanation.

Mike51merc. Maybe some one with a green book can give us some details of the variations of the big under diaphragm spring. My guess is there has to be more than one spring listed.

So why are pressure regulators made ,just curious :confused:

Pressure regulators are usually necessary when an electric fuel pump is installed, either to backup the stock mechanical one or to replace it. The lowest pressure electric pumps are still rated up to 4 lbs which is still higher than the 3.5 lb limit of the stock carbs. So, unless the electric pump is only turned only for a moment to "prime" the mechanical pump when vapor locked a pressure regulator is usually needed.
