Packard Forum Index » Pre-War (1899-1942)

I have a 1929 6-33 7 passenger touring that has sat for about 12 years. Apparently it was running when it was parked outdoors. I freed up the engine so it would turn over, installed a new battery, rebuilt the starter motor, changed all fluids etc.

I am not getting fuel from the tank to the carb. When I disconnect the hose to the carb and put a vacuum on it I do get gas flowing. Therefore it must be the fuel pump.

I know some have said the 1929’s didn’t have a fuel pump and it works via a vacuuum tank attached to the firewall. I have no vacuum tank and have an electric pump above the right rear tire as shown in the pic.

Has anyone seen this type of pump? Are they repairable? If not, what suggestions do you have??

Thanks

Having owned and driven two 633's and other similar models, for many years I strongly suggest reverting to a vacuum tank. There are new cheap electric pumps available but there are too many issues The vacuum tank is a simple and extremely reliable device that suits the carburetor and works extremely well.

G'day ‘29 633 Mel,
to PackardInfo.

I suggest you follow David's advice, he is quite the 633 Guru

I also invite you to include your '29 633 7 Passenger Touring in PackardInfo's Packard Vehicle Registry.

I doubt the old pump can be repaired.
Electric pumps are available, but they can be problematic on early cars. A vacuum tank system as originally equipped would deliver gasoline to the carburetor at a few ounces to perhaps a pound of pressure per square inch. Fuel pumps used on later Packards, such as mid 1930's models, typically delivered fuel at 3 to 4 pounds per square inch. If you used a modern, LOW PRESSURE electric pump with the early carburetor, a fuel pressure regulator would probably be needed to reduce the fuel pressure from around 4 to 7 pounds per square inch, or more, down to about 1 pound per square inch. In the interest of keeping the car original and complete, I'd try to obtain the correct vacuum tank system. If that proves to be impractical, a 6 volt, low pressure electric pump and regulator can be obtained, or a gravity tank and bypass system could be rigged up to simulate the original vacuum tank system.

for including your '29 Standard Eight Sedan in PackardInfo's Packard Vehicle Registry.

Thank you for the info. I am very much in the ‘keep it original’ camp. I am just completing an off the frame restoration of a ‘38 Dodge Coupe and went through great lengths to bring it back to ‘off the floor’ condition. So I am firmly in that camp.

The Packard is a rescue vehicle in that I observed the vehicle being left outside for almost a decade (sometimes with a tarp, sometimes not), and decided to contact the owner before it degraded too far. I now have the vehicle and am trying to get it running again, so it can be passed onto a new owner who will truly appreciate the vehicle. The ‘38 ate up my reserves, so keeping the Packard would be a shame as it would simply sit in the heated garage and not be enjoyed as it should.

I appreciate the info, and hopefully the next owner will do what I would’ve liked to have done - bring it back to ‘off the floor’ condition.

Thanks again

Mel

Ps, if anyone wants a 1929 633 7 passenger touring that is in a 6/10 condition, I am open for a discussion.

You are describing the reasons why these cars need a vacuum tank, not an electric fuel pump. The vacuum pump feeds by gravity at negligible pressure.

I would concur with David and get the Vacuum tank up and running. Even Rolls-Royce use them. This week I have had to go through the 34 P11 Autovac and with a six position fuel selector at the base of the Vacuum tank, it is not for the faint hearted. it is always handy to have an electric fuel pump but the vacuum tanks are simple and normally very reliable.

Actually a heated garage is not the best place to store a car as the heat promotes condensation. Better a constant cold temperature but not freezing.

I also recommend going back to vacuum. Once you have it working soundly it is a great system. I support the comments regarding electric pumps and issues regulating the inline fuel pressure feeding the carburetor. These 1929 Series 6 are Packard at their zenith, others who have them hold that view.
