Am considering installing electric fuel pump on my 40 Ford that has 59AB Block & rebuilt carb. It has been converted to 12 v. Any suggestions as to make & where they can be bought for our old cars. Thanks!

Will you be using the electric pump as your only pump or just for priming the carb after it has sat for a time? If it's your only pump you will have to add a pressure regulator as the stock carb will only tolerate about 3 pounds of pressure. You can get electric pumps at your local Napa Auto Parts or other parts stores. Do not get a pump with a rubber diaphram. Get a rotary style pump as they will tolerate all types of gas including methanol.Here's some pump numbers: AC #EP425,Carter # P4070, Airtex E18016, Auto Zone Masterbrand E8016S. I think these are 12 volt part numbers, but double check with your parts person.

We use the Airtex pump sold by C&G. It is available in both 6 and 12 volt types. You can see it on page 125 of their on-line catalog. www.cgfordparts.com It is quiet and, in our opinion, is better than any others we have tested.

ever consider rebuilding the original fuel pump ? OLD PARTS CELLAR has some great kits,or will rebuild yours, I rebuilt my pump using their parts,and installed the copper washers for the antifeedback of the fuel so the car will start after sitting for a few months,and this was 5 years or more with no problems as of yet, my car sat from DEC to MAY, and it started with out PRIMING the carb,and NO ELECTRIC PUMP,,,, and 6 volts,, the electric pumps are good if you want to use more carbs then one, you should ad a fuel pressure regulator, like was said before, and be careful were you mount it, hope this helps 37RAGTOPMAN,,, KEEK ON TRUCKIN,!!!!!!

Can someone explain the use of "copper washers to prevent feedback of fuel"? I have thae same problem with my '32 pickup, in which I run a '34 carb.

I don't understand carb "feedback". If the valves in the fuel pump are OK, the gas can't be siphoned from the carb, and even if so, the high float needle position will break the siphon.

The fuel feedback leak has nothinng to do with the valves in the fuel pump or carb float level, it leaks back from the flex line.IT WERE THE FLEX LINE joins the line on the firewall and the line going into the fuel pump,it does not have to be much, a very little air will keep the pump from working correctly, and making starting a long process, I had a problem for many many years,bought the copper washers from OLD PARTS CELLAR, and had no problems yet and it's been years, last time it sat for 3 months and it started without priming it cranked a few times but that is ok so it will build up a little oil pressure before it fires, Look,,,if you want to keep dumping raw gas every time you car sits for a period of time, just keep doing so, I wish to repair the problem, instead of living with it. the washers are only about $2.00 each not alot of money for what they do, I also bought a new fuel flex line and installed them together, call 781-335-8860 or www.then-now.com they are in WEYMOUTH,MASS I think the owners name is TOM, give them a try , it might work for you what do you have to loose ? also you may also have a small fuel drip from the 2 carb main jet screw plugs on the float bowl,hard to detect over a long period of time,need 2 new fiber gaskets, HAVE GOOD CARB KITS AND FUEL PUMP KITS for modern fuels,I have no ties to this business, just passing good info when I find a good place to do business with, I try staying away from the CHINA TAIWAN,DEALERS. hope this helps, KEEP ON TRUCKIN 37RAGTOPMAN This message was edited by 37RAGTOPMAN on 6-6-10 @ 8:20 AM

The usual reason for loss of fuel in the carb bowl is the evaporation caused by "heat soak" after shutdown. Any air leak or vapor in the fuel system can cause loss of prime in the fuel pump. That is why "vapor lock" was often cited as a problem when fuel in the line was subjected to a heat source. It was, more often, a failing ignition coil. Given the displacement of the float, the carb actually holds very little fuel, and any leakage, such as at the power valve gasket or other seals in the carb body, will cause the gas odor. Today's gas has a high amount of volatile compounds and evaporates quickly in unconfined spaces. Perhaps the "copper washers" simply provide a better seal. There doesn't seem to any other reason they would be needed.

super,,,,!!!!!!!!!! now you have it,a better seal, cars sitting for months at a time do funny things, was just trying to get the V8 CLUB MEMBERS,there is a way of fixing there fuel problems with out adding a electric fuel pump, I am positive 60 years ago, the FORD DEALERS did not install a electric pump on these cars, one thing , is your cam shaft rear lobe for the fuel pump has to be in good condition,and has to move the arm all the way up and down, if that is not good, go to the electic pump it is easier then installing a new camshaft, if my fuel pump were to fail on the road I would put a electric pump to get me home,and rebuild the original again, PARTS CELLAR sells excellant kits with modern materials so you do not have problems with modern fuels, if you install a electric pump you have to make sure you have the correct pressure, or you will have more problems like gas spilling out and flooding the engine, if the needle and seat gets stuck or the float gets stuck. or to much pressure, my 3 cents worth 37RAGTOPMAN KEEP ON TRUCKIN,,,,!!

Rag: I'm glad we agree. It is possible you had one or more of the usual hairline cracks in your flex line when you replaced it and installed the washers. That is the weak link in the old Ford fuel system, as it is subjected to almost constant flexing as the engine moves on the mounts. I don't recommend that everyone install an electric fuel pump. I did it because it reduces the amount of cranking after a long period of inactivity. When I was having problems with the old fuel line, it did get me home more than once, and sure beats trying to replace a fuel pump on the side of the road, particularly at night. I look at it as a backup, sort of like the spare tire. The Airtex pumps we use maintain between 3 and 4 lbs pressure, so we don't use a regulator, and have had no problems with overflow. As for camshafts, in over sixty years in the business, I haven't had to replace an original camshaft unless an oil pressure failure occurred. One can only wish modern cams were as tough, as we replace many of those.

I still don't see the need for the copper washers or understand how they would fit in the fuel pump and the flex line. I have gone to the Antique Auto Cellar web site and cannot find any reference to these washers or a photo of them. Maybe you could post a photo of them to help clear up the confusion. When I look at the two types of fuel pumps for the V-8, I cannot see how fuel could be siphoned out of the sediment bowl. Fuel in the line from the tank will only drop back until it reaches the level in the tank, and it would only leak back if there was an air leak in the sediment bowl gasket or in the flex line connection. This would also make it difficult for the fuel pump to prime itself. Fuel will leak out of the carburetor through the drain plug gaskets and the power valve gasket. It will also travel by capillary action through the open power valve, past a leaking accelerator pump discharge needle (P/N 78-9594). Heat soak starts this action, but it can start on own if the needle seat is badly corroded. Tom

TOMO did you call them? Call them and let us know what they said remember they cannot have evertyhing on the web site, the copper washers are tapered, if you do not believe me forgetaboutit I am getting tired of trying to prove that these work , if you do not believe leave it at that, I HAVE NO PICTURES, [ I wish I did ] I installed them and do not want to distrub something that is working for me, KEEP ON TRUCKIN,37RAGTOPMAN also the fuel does not drain out of the fuel pump,air leaks in the line at the fuel line fitting, leaving air in,so it makes it hard for the fuel pump to regain prime, after sitting there is certain amount of vaporation in the carb,so it is not full of fuel and with some air in the line it makes it hard for the fuel pump to work, when first starting after sitting for period of time, why do you think a guy puts one way valves in the fuel lines that he makes,??? it keeps the fuel from going back to the tank,leaving air in the feedline, This message was edited by 37RAGTOPMAN on 6-7-10 @ 4:52 PM
