What's in the Box

Carter rotary vane universal electric fuel pumps were originally created for military use. This time-tested design has been in production longer than any other Carter model. Rotating vanes driven by a heavy-duty wet six volt motor deliver 5-3/4 PSI max pressure and a flow rate up to 72 GPH. This provides excellent lift and prime capability when the pump is mounted below the lowest point of the fuel tank at the rear of the car.

The inlet and outlet ports are 1/4" NPT. The pump comes with two 1/4" NPT to 3/8" hose barb adapters, two short electric leads, and a mounting bracket with rubber isolators. 

  • 6 volt electric motor
  • Operates on positive or negative ground
  • Rated at 72 GPH and 5-3/4 psi max pressure
  • Includes barbs for 3/8" hose and mounting bracket
  • Suitable for most RV, marine, agricultural, industrial and performance applications

Absolutley Great Unit

January 27, 2015
I restore a lot of cars and work with a lot of suppliers. Sometimes I need to improvise to replace parts that simply are not obtainable. I can say, without any reservations, that Speedway is one of the best in the business. They actually work at making sure your taken care of. Not the case with a lot of suppliers. I have purchased other products from Speedway. This fuel pump is top quality, like everything else they sell.
Pros:
  • totally overbuilt
Cons:
  • Can't think of any
Yes, I recommend this product.

It may, but I would suggest purchasing a pressure regulator, with your pump. I bought an Ofenhauser adjustable regulator, from Speedway. It is much wiser to get a powerful pump and regulate it, than wind up with inadiquate volume. I had to mount it in the trunk and still wound up running it at 4 psi. The regulator is quite inexpensive.

It will depend upon your carburetor as to the pressure it will handle. You shouldn't have an issue going from 4.5 to 5.75 psi on modern carburetors but some of the 40's and 50's carbs as well as previous to that can only handle about 3 psi max.

This 6 volt electric fuel pump is internally regulated to 5 ¾ psi max. If using in conjunction with a mechanical fuel pump at the engine and concerned about regulating the pressure at the carburetor I would suggest installing a pressure regulator between the mechanical pump and the carburetor. Some customers use the electric to get fuel to the mechanical when the vehicle sits for an extended time period to help eliminate the need for lengthy cranking of the engine to get fuel to the motor and then shut the electric off once started and sufficient fuel is available in the lines. Fuel will flow through when not running.

It should work fine. You will have to secure a ground wire, as it sounds like your old pump may ground through the mounting bracket. This pump will work on either positive or negative ground, but you will need to experiment to determine which terminal to ground, to make sure the pump is running the right direction. It will not pump anything if it is running backwards.

This fuel pump works on negative or positive ground through two lead wires. The pump includes rubber isolators to help with noise radiating through the vehicle and without positive and negative hook ups would not function properly. Some of the other pumps were basically a power lead only and grounded through the mount.

A regulator would be installer immediately downstream of the electric pump, which should be mounted as close to the tank as possible. It is important to get an adjustable regulator. Speedway has them available at a very reasonable price. Why do you need a "booster" pump? It would be a good idea to check performance on your mechanical pump. Make sure it is functional. It might be wise to just replace it, if one is available.

Because this pump is comparable with either ground configuration, you will not find a + or - marked on the unit. Once the fuel lines are installed you need to momentarily hook it up and make sure it is pumping. When it's right you can then "hardwire" the unit.
May 18, 2011

On a negative ground vehicle the positive lead feeds power to the switch and from the switch to the positive side of the pump. In reverse on a positive ground vehicle the negative is actually the power source and feeds the power or positive lead on the pump. This pump will work either way whereas many other pumps are strictly negative ground. Verify flow once everything is connected and plumbed.

Part # 9104259 This is strictly a 6 volt pump and use on a 12 volt system would require a voltage reducer such as part number 91064103.

Answers

No. It will lift, when mounted above the pick-up tube. It does have limitations, but I had to mount it about 16 inches above the bottom of the tank and it works great. Also, make sure to leave room for a good quality, easily replaced filter between the tank and the pump. As to "anywhere in the line", the answer is no. It needs to be in close proximity to the tank. Electric fuel pumps push fuel much better than they pull it.
September 15, 2011

Speedway part number 9104259. It would be best to mount any electric fuel pump below the lowest point of your fuel tank. Electric fuel pumps push far better than they pull fuel, and the less they need to pull fuel the longer they will last. You could run it above the low point of the fuel tank but the pump may fail prematurely.

This pump is NOT adjustable for pressure supplied. If needing to reduce the pressure at the carburetor we recommend our low pressure regulator number 56058500 and the appropriate fittings for your fuel line. We also offer the Holley version number 42712804 if preferred/
