Has anyone had an electric fuel pump that lasted a long time?

I've been using a Carter P4070 a little over a year and earlier tonight it left me sitting along the side of the road.
My wife went to parts store and picked up a cheap Precision that I zip tied on to get home.

I'll pay big for one that will last.

Thanks!!

I ran a Holley pump for years, many miles, but it was loud.
 
I have a who knows what brand pump that has been installed since before I got the car. Works fine, I wait to hear the pump quiet down after the fuel reaches the carb, and hit the pedal a few times before cranking it over and it fires right up. Ghetto as hell, way up on the frame rail.

Thanks, I'm leaning towards a Holley.

The Carter was loud as hell too. The little Precision I put on to get home is quiet. Wasn't even sure the thing was pumping!
 
I'm running a regulator but no return. It's been fine until tonight. When it quit it got real quiet, like a hummm instead of a pump.

The P4070 is rated at 4psi but it was pumping about 5.750 and I regulated it down to 5. It's also rated at 72 gpm where the one you posted is 100 gpm.

That's unusual. I plan on gettin one of these soon as I am going to get the fuel system done on the rat truck. Of course it will need a regulator and return system.

I like the Aeromotive stealth 340 pumps. They mount in the fuel tank. Coupled with a good return and their carburetor bypass return regulator, you’d have a good setup.

That's what did it. Those type pumps are not dead head happy. They will last with a return. I wouldn't recommend that style again if you plan on running dead head.
 
I use a Holley on the car and the pick-up. Like mentioned above, it's loud, but at least I know when it's running. Once the big block fires, I don't hear the pump anymore.

Dang, I never thought about running a return.
 
Whisper quiet and runs my dual quads without any problems...

A return will add life to any electric fuel pump and will even help some high delivery mechanical pumps. It kinda gives them a little "relief". Helps them run cooler and last longer. Not to mention the benefits on the fuel end. But you can run a dead head system just fine too. People have done it for decades.
 
I think I'll run it dead head until winter, then replace the original feed line and add a return.

I'll just carry a spare pump with me at all times!!

I have an Edelbrock pump for sale here on FABO. Look it up and make me an offer.
 
That's the first time I have heard of Carter elec pump failing. Was it's electrical supply checked out to see if it was getting the full 12v?
 
I am a huge fan of In-tank pumps for most applications. They can support most reasonable power for the majority of the builds I have seen in my lifetime..... Quiet, easy install, reliable, and just makes sense... Everyone slices pizza a different way and that's how I would do a street bruiser with an electric pump in today's world...

It surprised me too.

I'll check it today to see if the full 12v are there. But as soon as the new one was hooked up, it fired up.

I hear ya, pun intended, I avoid electric pumps for many reasons. I much prefer a high performance mechanical pump for a street application.
 
In my opinion, ANY motor drive pump that is "dead head" whether it's working against a (closed) needle/ seat, or a regulator, is subject to problems. The rotor sits there churning and cavitating and making heat.

Investigate if there is an old fashioned "pulser" that is electronic and reliable. I once had one, forgotten the name. 'In it's day' it was a LARGE pump, larger than the Bendix/ AC pulsers which had electrical contacts. This one was electronic. I had that thing for a few years, it finally failed

You can run a fuel return off the regulator to avoid this ^^^^^^issue.
