    P4389 - Carter Universal Marine Electric Fuel Pumps is rated 3.6 out of 5 by 8.
    Rated 5 out of 5 by from Works perfectly My boat hadn't been run in 2 years because the old fuel filter was shot. Got this one delivered quickly, it installed easily and works perfectly. I ordered it by phone because I had some questions on the intake size and flow rate. The gentleman on the phone was very helpful.

    Rated 5 out of 5 by from Marine Power 6.0 pump replacement Boat (2005 North River) had vapor lock symptoms. After trying everything else, I decided to replace the low pressure pump. Direct replacement except the wire connectors which were easily swapped with the included ones. Vapor lock problem solved. This part was reasonably priced and arrived in about a week. I saved hundreds doing the job myself and the repair shop was booking two months out so I got it done and back on the water.

    Rated 3 out of 5 by from Carter marine electric fuel pump Carter marine electric fuel pump The pump worked extremely well the electrical connections were a disappointment. I didn’t trust the plug on connectors so I solder the wires to the terminals. If they came up with a better terminal/connector I would say this is an excellent pump

    Rated 1 out of 5 by from Ordered two P4389 received 2 different pumps I ordered 2 P4389 marine Fuel pumps. I was sent two different pumps in two Different boxes one was clearly marked made in China the other was a Carter made in USA. They were both clearly different in the way they were manufactured. I called support to point this out and I was told to send it back and they would exchange it for an original at my expense this is unacceptable! Furthermore the one made in China isn’t on there web site, Buyers beware!

    Will this pump feed a 440 sixpack and can it be regulated

    Asked by: cratos
    Yes, this should put out enough volume for a 440 six pack engine. You can always add a regulator.

    If I use this pump to feed a mechanical pump will it stop vapor lock?. I live in Arizona, where it gets to 105 in a jiffy.

    Asked by: Desert Guy
    This may help your vapor lock situation, you may try running the electric by itself.

    How many amps does it draw. Does it have to be mounted below fuel level.

    Asked by: jerrald
    It will be more efficient below the level of the tank, but will work even if above it. These pumps normally draw between 3-5 amps.

    When I received the pump it came with two black wires. I can not find any markings on the pump that identify which electrical connection is positive. Does it mater or do I connect it up using my best guess?

    Asked by: ronrw2b2
    Yes it does matter. the posts are marked with a + and - symbols for proper connections.
