Carter electric pump

[Doug&Deb]

I know some of you are using the Carter P4259 pump successfully. I’m not here to debate the merits of electric versus mechanical but I’m curious about whether anyone using this has a newer pump. Mine is made in China which is a concern. I’m not sure yet if I’m going this route but after fighting a fuel problem for a few months I’m considering it. Any thoughts on the reliability of the new pumps?

reliability with offshore aftermarket stuff is a roll of the dice though Carter is still a better brand...6 volts is your limitation with choices and the Carter with the isolated motor this unit swings both ways with no problem.  I went with an aftermarket and surely offshore made unit as my intent is to use as a primer only.   Whatever you decide, pusher setup is the better way to go, isolation mounts to prevent hammering is really a must if you intend to use as main delivery pump.

I don't have anything to offer other than just try it. I think the Carter, even if built offshore, would have better reliability than a Ching Whang Chong or other unknown brand. I don't know where the Carter in my P15 was built but it has been flawless for four and half years.

Thanks guys. Decisions decisions.

What makes you think there is any difference other than the name on the box?

Nothing is making me think anything. All I stated is that "Carter" is an American brand and much of the items I get on Amazon are not.

 

Buy what makes you happy...................

Let me clarify, since the pump is now made in China what makes you think there is any difference from a "Ching Whang Chong or other unknown brand" other than the name on the box?

I haven't seen a 6v pump that resembles the Carter from any other brand than Carter. May be one out there but it seems this particular pump is unique to Carter.

Let's hope so

Any idea what the Carter pump puts out as far as pressure?  Can the mechanical pump still draw fuel through it when not in use?  Needle and seat can still operate?

The Carter spec page doesn't list pressure output:

However, I have about twelve years history with these pumps on two cars and never had an issue with the carb needle valve, the pumps have been flawless with no regulator.

 

I don't know the answer to your question about fuel draw through the inactive pump, I've only used it as a full-time pump with no mechanical pump. If I only wanted a primer or backup pump to use with a mechanical I would install one of the smaller, cheaper pumps....(and carry a spare?).

The in line “clicker” type pumps can be setup to draw through, and put inline with a mechanical pump. They also come rated at 5 psi max, which is perfect for our carburators. I had mine like that for a while as a primmer, or for when it started ‘vapor locking’ in the heat. I have since changed it to be plumbed in parallel. 

 

This one that you reference appears to be a rotary vane pump. You won’t be able to draw through that one, and you’ll likely need a pressure regulator to go with it. 

[Sam Buchanan]

I crawled under the car to take a look at the Carter pump but couldn't see any country of origin markings. Yes, it is indeed a rotary vane pump, see the spec sheet I linked above.

 

And...as I have stated several time previously I haven't had to use a regulator on either of the cars with the Carter pumps.

I bought this one in 2018 for the Plymouth as a primer/backup pump. It has been working great and the mechanical fuel pump has no problem drawing through it. It puts out approx 6 psi and I use a spring loaded off switch to activate it. I haven't had to use it for a primary to get me home, so I can't verify its worthiness on that aspect of it, but as a primer it's been great.

that basic pump can be found in a box with a myriad of names  on the label.....  They are not expensive, they are easy to install and if you buy one, buy two if using as the primary pusher so you will never be stranded....connectorized them the same and swap on the highway is bing bam boom done...failure to have a redundancy plan is on you more than the fault of the product.
