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

I bought this pump to use as a lift pump for my 2001 LB7 Silverado Duramax. I haven't fitted it yet, but have tested it. It pumps approximately 5 litres in 1 minute 4 seconds (see video) so is very close to the stated flow rate. It is self-priming, no reviews mentioned this, I tried to add a video, but Amazon only allows 1 video per review for whatever reason. I'm quite pleased with the above results, however, I also tried sucking fuel through it with another pump whilst this one was off and it didn't like it at all, if the pump stops working for any reason, mechanical or electrical failure, the pump on the engine will likely not be able to suck it through and put unwanted strain on it, which could potentially stall the engine, I will try this theory when it's fitted to the truck, but even so, it would be wise to carry a spare peice of fuel hose to replace the pump in an emergency. All told, I recommend this pump.

Tengo un año usándola en mi camioneta chevrolet carburada con motor v8 7.4 L y estoy más que contento con ella. Puso fin a todos mis problemas con la bomba mecánica original, eliminó el problema de vapor lock que tenía al subir pendientes prolongadas y/o en condiciones de calor extremo. Además el flujo es constante y no por pulsos, lo que hace que el motor se sienta mucho más parejo y suave. Es cierto que es un poco ruidosa, pero no molesta y con el motor andando casi no se escucha. No necesita regulador de presión y proporcina un alto flujo ideal para motores de gran cilindraje. El arnes de cableado, si se instala correctamente, funciona bien y no se bota o safa, pero hay que meter empujar los hules con fuerza hasta el fondo, el hule de los capuchones es poco flexible pero al final con la fuerza suficiente, el hule cederá y entrará sobre las "bases blancas", al final no olvide poner el clip para mayor seguridad. No use ningún tipo de sellador en las conexiones roscadas para las mangueras y no presentan fugas, pero para lograrlo deben ser apretadas con torque bastante considerable para que efectivamente queden estancas. Procure encender el auto por lo menos una ves al mes para evitar que la bomba se vacíe, en lo ideal debe permanecer permanentemente llena de combustible para evitar oxidación interna.

I like Carter products, it works great. One problem it was shipped with wrong fuel fittings. I ordered 3/8 by 3/8 fuel fittings, it came wit larger threads and does not fit the pump.Wires are too short, has appropriate pressure and no leaks. Sender owes me the right fuel fittings, 3/8 threads by 3/8 barbs

I have been running this pump for two years now. It feeds a quadrajet on a 305 SBC. I’m not sure how many miles it’s seen as my odometer is dead but I daily the car. This week for instance I did 500 km. It is loud but like others have said that is handy on an old hotrod project, so you know it’s running. I bought a second one and keep it in the trunk for the day it does eventuality die. I would recommend.
