Carter Universal Electric Fuel Pump Automotive Replacement 12V (P4070)

Was having a problem with the electric fuel pump (brand new) on my classic car restoration, pump would stop pumping and leave me stranded. This pump required some modifications to fit in my application and elbow fittings to allow angled install of the fuel lines, but the engine now runs like it should and doesn't leave me stranded. Previous comments on the snap-on electrical connectors didn't appear to be a problem, when snapped completely in place they were very difficult to remove?

Mine has only been on for 300 miles. I’m still shaking out a new Jeep build. I have a Weber carb which requires low pressure. I mounted this under the hood, which is not the way it’s intended to be used. I suppose everyone knows that they are pushers and not pullers. However, I wanted easy access to the pump and have a gauge on it to see the fuel pressure just by raising the hood. I put a heavy duty piece of 2” hose between the pump mount and the chassis to eliminate any vibes and I have none. I can’t hear the pump running even at idle. I have no pressure regulator and it sits at 3psi, perfect for my application. I only have 300 miles on it so far but have no problems. I did install the recommended low oil pressure shut off, and it does cut the pump off as it should when I unplugged it (cuts power to pump).

Works good for auxiliary fuel tank pump

I had a Holley pump on my hotrod pickup truck makes 350ish HP and it siezed up from sitting for couple years but I always hated that pump because it was soooooo loud, as soon as I turn on the key I'd have to listen to that horribly loud growl they make until I shut it off, when I was replacing if I thought I'll try this one it says it's quiet and it's not one of those tiny cheap $12 pumps and wow huge difference you can barely hear it outside and not at all inside. The only issue I had was those damn electrical connectors that just pop on because they pop off just as easy. That issue has left me dead in the middle of an intersection and on side of a busy road, it only took a second to jump out pop em back on but jumping out an crawling under my truck to pop the wire back on in the middle of a busy intersection or cars whizzing by is less than ideal, so it has electrical tape wrapped around it holding the wires on, it was temporary but it worked so I never bothered to do a permanent fix on but other than that it's a great reliable very quiet pump.

These pumps are ridiculously bad. In case you think I am maligning a decent parts manufacturer because I slapped a pump into an old clapped out junker with crappy wiring or bad grounds or couldn't figure out the oddball electrical connectors, no, that's not the case--I did everything right, installed it below the tank far from the engine bay, used oversized wire, triple checked everything, making sure the grounds were excellent and the voltage at the pump was within spec and the ground was at 0.0 ohms, and still this pump lasted about an hour. I drove around the neighborhood, was pleased with the pressure (~4.5 PSI), but the next day started the car up and noticed the pump was a bit noisier than it had been the day before, and I could hear it clearly above the idling engine. Now the pressure was 6 PSI, and after about ten minutes it dropped off to less than 1PSI then down to zero and the car died at idle a minute later. I let everything cool off, checked and double checked everything, and restarted it. The same thing happened. I even measured the temperature of the pump, to make sure it wasn't heating up. I repeated this process a few times, then removed it, put in another brand new identical pump I'd bought for a backup, and the second pump was even worse, making about 1 PSI. The car would starve for fuel at anything over idle. The second pump was quieter than the first, but still sounded "off," not at all healthy. I can't be sure, but I suspect Carter pulled the old trick of moving manufacturing overseas to a factory with inadequate quality control, and are simply getting people to buy these pumps based on familiarity and brand recognition because they are technically OEM for several models. I would be surprised if Carter are in business in five years if they keep building parts like this. I would use anything rather than one of these pumps again, Holley, Mr. Gasket, Facet, or even some no-name knockoff. This is the worst pump I have ever seen, worse than garbage because it almost sort of wants to work, and if you didn't have a pressure gauge you'd be left scratching your head. FYI, I installed a Facet pump and everything works fine.
